| CVE-2022-50840 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: scsi: snic: Fix possible UAF in snic_tgt_create() Smatch reports a warning as follows: drivers/scsi/snic/snic_disc.c:307 snic_tgt_create() warn: '&tgt->list' not removed from list If device_add() fails in snic_tgt_create(), tgt will be freed, but tgt->list will not be removed from snic->disc.tgt_list, then list traversal may cause UAF. Remove from snic->disc.tgt_list before free(). | ||||
| CVE-2022-50839 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: jbd2: fix potential buffer head reference count leak As in 'jbd2_fc_wait_bufs' if buffer isn't uptodate, will return -EIO without update 'journal->j_fc_off'. But 'jbd2_fc_release_bufs' will release buffer head from ‘j_fc_off - 1’ if 'bh' is NULL will terminal release which will lead to buffer head buffer head reference count leak. To solve above issue, update 'journal->j_fc_off' before return -EIO. | ||||

| In the Linux kernel, the following vulnerability has been resolved: net: stream: purge sk_error_queue in sk_stream_kill_queues() Changheon Lee reported TCP socket leaks, with a nice repro. It seems we leak TCP sockets with the following sequence: 1) SOF_TIMESTAMPING_TX_ACK is enabled on the socket. Each ACK will cook an skb put in error queue, from __skb_tstamp_tx(). __skb_tstamp_tx() is using skb_clone(), unless SOF_TIMESTAMPING_OPT_TSONLY was also requested. 2) If the application is also using MSG_ZEROCOPY, then we put in the error queue cloned skbs that had a struct ubuf_info attached to them. Whenever an struct ubuf_info is allocated, sock_zerocopy_alloc() does a sock_hold(). As long as the cloned skbs are still in sk_error_queue, socket refcount is kept elevated. 3) Application closes the socket, while error queue is not empty. Since tcp_close() no longer purges the socket error queue, we might end up with a TCP socket with at least one skb in error queue keeping the socket alive forever. This bug can be (ab)used to consume all kernel memory and freeze the host. We need to purge the error queue, with proper synchronization against concurrent writers. | ||||
| CVE-2022-50837 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: net: dsa: tag_8021q: avoid leaking ctx on dsa_tag_8021q_register() error path If dsa_tag_8021q_setup() fails, for example due to the inability of the device to install a VLAN, the tag_8021q context of the switch will leak. Make sure it is freed on the error path. | ||||
| CVE-2022-50836 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: remoteproc: sysmon: fix memory leak in qcom_add_sysmon_subdev() The kfree() should be called when of_irq_get_byname() fails or devm_request_threaded_irq() fails in qcom_add_sysmon_subdev(), otherwise there will be a memory leak, so add kfree() to fix it. | ||||

| CVE-2022-50625 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: serial: amba-pl011: avoid SBSA UART accessing DMACR register Chapter "B Generic UART" in "ARM Server Base System Architecture" [1] documentation describes a generic UART interface. Such generic UART does not support DMA. In current code, sbsa_uart_pops and amba_pl011_pops share the same stop_rx operation, which will invoke pl011_dma_rx_stop, leading to an access of the DMACR register. This commit adds a using_rx_dma check in pl011_dma_rx_stop to avoid the access to DMACR register for SBSA UARTs which does not support DMA. When the kernel enables DMA engine with "CONFIG_DMA_ENGINE=y", Linux SBSA PL011 driver will access PL011 DMACR register in some functions. For most real SBSA Pl011 hardware implementations, the DMACR write behaviour will be ignored. So these DMACR operations will not cause obvious problems. But for some virtual SBSA PL011 hardware, like Xen virtual SBSA PL011 (vpl011) device, the behaviour might be different. Xen vpl011 emulation will inject a data abort to guest, when guest is accessing an unimplemented UART register. As Xen VPL011 is SBSA compatible, it will not implement DMACR register. So when Linux SBSA PL011 driver access DMACR register, it will get an unhandled data abort fault and the application will get a segmentation fault: Unhandled fault at 0xffffffc00944d048 Mem abort info: ESR = 0x96000000 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x00: ttbr address size fault Data abort info: ISV = 0, ISS = 0x00000000 CM = 0, WnR = 0 swapper pgtable: 4k pages, 39-bit VAs, pgdp=0000000020e2e000 [ffffffc00944d048] pgd=100000003ffff803, p4d=100000003ffff803, pud=100000003ffff803, pmd=100000003fffa803, pte=006800009c090f13 Internal error: ttbr address size fault: 96000000 [#1] PREEMPT SMP ...

| CVE-2023-45896 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.1 High |
| ntfs3 in the Linux kernel through 6.8.0 allows a physically proximate attacker to read kernel memory by mounting a filesystem (e.g., if a Linux distribution is configured to allow unprivileged mounts of removable media) and then leveraging local access to trigger an out-of-bounds read. A length value can be larger than the amount of memory allocated. NOTE: the supplier's perspective is that there is no vulnerability when an attack requires an attacker-modified filesystem image. | ||||

| CVE-2022-50560 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/meson: explicitly remove aggregate driver at module unload time Because component_master_del wasn't being called when unloading the meson_drm module, the aggregate device would linger forever in the global aggregate_devices list. That means when unloading and reloading the meson_dw_hdmi module, component_add would call into try_to_bring_up_aggregate_device and find the unbound meson_drm aggregate device. This would in turn dereference some of the aggregate_device's struct entries which point to memory automatically freed by the devres API when unbinding the aggregate device from meson_drv_unbind, and trigger an use-after-free bug: [ +0.000014] ============================================================= [ +0.000007] BUG: KASAN: use-after-free in find_components+0x468/0x500 [ +0.000017] Read of size 8 at addr ffff000006731688 by task modprobe/2536 [ +0.000018] CPU: 4 PID: 2536 Comm: modprobe Tainted: G C O 5.19.0-rc6-lrmbkasan+ #1 [ +0.000010] Hardware name: Hardkernel ODROID-N2Plus (DT) [ +0.000008] Call trace: [ +0.000005] dump_backtrace+0x1ec/0x280 [ +0.000011] show_stack+0x24/0x80 [ +0.000007] dump_stack_lvl+0x98/0xd4 [ +0.000010] print_address_description.constprop.0+0x80/0x520 [ +0.000011] print_report+0x128/0x260 [ +0.000007] kasan_report+0xb8/0xfc [ +0.000007] __asan_report_load8_noabort+0x3c/0x50 [ +0.000009] find_components+0x468/0x500 [ +0.000008] try_to_bring_up_aggregate_device+0x64/0x390 [ +0.000009] __component_add+0x1dc/0x49c [ +0.000009] component_add+0x20/0x30 [ +0.000008] meson_dw_hdmi_probe+0x28/0x34 [meson_dw_hdmi] [ +0.000013] platform_probe+0xd0/0x220 [ +0.000008] really_probe+0x3ac/0xa80 [ +0.000008] __driver_probe_device+0x1f8/0x400 [ +0.000008] driver_probe_device+0x68/0x1b0 [ +0.000008] __driver_attach+0x20c/0x480 [ +0.000009] bus_for_each_dev+0x114/0x1b0 [ +0.000007] driver_attach+0x48/0x64 [ +0.000009] bus_add_driver+0x390/0x564 [ +0.000007] driver_register+0x1a8/0x3e4 [ +0.000009] __platform_driver_register+0x6c/0x94 [ +0.000007] meson_dw_hdmi_platform_driver_init+0x30/0x1000 [meson_dw_hdmi] [ +0.000014] do_one_initcall+0xc4/0x2b0 [ +0.000008] do_init_module+0x154/0x570 [ +0.000010] load_module+0x1a78/0x1ea4 [ +0.000008] __do_sys_init_module+0x184/0x1cc [ +0.000008] __arm64_sys_init_module+0x78/0xb0 [ +0.000008] invoke_syscall+0x74/0x260 [ +0.000008] el0_svc_common.constprop.0+0xcc/0x260 [ +0.000009] do_el0_svc+0x50/0x70 [ +0.000008] el0_svc+0x68/0x1a0 [ +0.000009] el0t_64_sync_handler+0x11c/0x150 [ +0.000009] el0t_64_sync+0x18c/0x190 [ +0.000014] Allocated by task 902: [ +0.000007] kasan_save_stack+0x2c/0x5c [ +0.000009] __kasan_kmalloc+0x90/0xd0 [ +0.000007] __kmalloc_node+0x240/0x580 [ +0.000010] memcg_alloc_slab_cgroups+0xa4/0x1ac [ +0.000010] memcg_slab_post_alloc_hook+0xbc/0x4c0 [ +0.000008] kmem_cache_alloc_node+0x1d0/0x490 [ +0.000009] __alloc_skb+0x1d4/0x310 [ +0.000010] alloc_skb_with_frags+0x8c/0x620 [ +0.000008] sock_alloc_send_pskb+0x5ac/0x6d0 [ +0.000010] unix_dgram_sendmsg+0x2e0/0x12f0 [ +0.000010] sock_sendmsg+0xcc/0x110 [ +0.000007] sock_write_iter+0x1d0/0x304 [ +0.000008] new_sync_write+0x364/0x460 [ +0.000007] vfs_write+0x420/0x5ac [ +0.000008] ksys_write+0x19c/0x1f0 [ +0.000008] __arm64_sys_write+0x78/0xb0 [ +0.000007] invoke_syscall+0x74/0x260 [ +0.000008] el0_svc_common.constprop.0+0x1a8/0x260 [ +0.000009] do_el0_svc+0x50/0x70 [ +0.000007] el0_svc+0x68/0x1a0 [ +0.000008] el0t_64_sync_handler+0x11c/0x150 [ +0.000008] el0t_64_sync+0x18c/0x190 [ +0.000013] Freed by task 2509: [ +0.000008] kasan_save_stack+0x2c/0x5c [ +0.000007] kasan_set_track+0x2c/0x40 [ +0.000008] kasan_set_free_info+0x28/0x50 [ +0.000008] ____kasan_slab_free+0x128/0x1d4 [ +0.000008] __kasan_slab_free+0x18/0x24 [ +0.000007] slab_free_freelist_hook+0x108/0x230 [ +0.000010] ---truncated--- | ||||

| CVE-2022-50564 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: s390/netiucv: Fix return type of netiucv_tx() With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG), indirect call targets are validated against the expected function pointer prototype to make sure the call target is valid to help mitigate ROP attacks. If they are not identical, there is a failure at run time, which manifests as either a kernel panic or thread getting killed. A proposed warning in clang aims to catch these at compile time, which reveals: drivers/s390/net/netiucv.c:1854:21: error: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Werror,-Wincompatible-function-pointer-types-strict] .ndo_start_xmit = netiucv_tx, ^~~~~~~~~~ ->ndo_start_xmit() in 'struct net_device_ops' expects a return type of 'netdev_tx_t', not 'int'. Adjust the return type of netiucv_tx() to match the prototype's to resolve the warning and potential CFI failure, should s390 select ARCH_SUPPORTS_CFI_CLANG in the future. Additionally, while in the area, remove a comment block that is no longer relevant. | ||||
