| In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix double release compute pasid If kfd_process_device_init_vm returns failure after vm is converted to compute vm and vm->pasid set to compute pasid, KFD will not take pdd->drm_file reference. As a result, drm close file handler maybe called to release the compute pasid before KFD process destroy worker to release the same pasid and set vm->pasid to zero, this generates below WARNING backtrace and NULL pointer access. Add helper amdgpu_amdkfd_gpuvm_set_vm_pasid and call it at the last step of kfd_process_device_init_vm, to ensure vm pasid is the original pasid if acquiring vm failed or is the compute pasid with pdd->drm_file reference taken to avoid double release same pasid. amdgpu: Failed to create process VM object ida_free called for id=32770 which is not allocated.

| In the Linux kernel, the following vulnerability has been resolved: drm/msm: fix use-after-free on probe deferral The bridge counter was never reset when tearing down the DRM device so that stale pointers to deallocated structures would be accessed on the next tear down (e.g. after a second late bind deferral). Given enough bridges and a few probe deferrals this could currently also lead to data beyond the bridge array being corrupted. Patchwork: https://patchwork.freedesktop.org/patch/502665/ | ||||

| In the Linux kernel, the following vulnerability has been resolved: drm: bridge: anx7625: Fix NULL pointer dereference with early IRQ If the interrupt occurs before resource initialization is complete, the interrupt handler/worker may access uninitialized data such as the I2C tcpc_client device, potentially leading to NULL pointer dereference. | ||||
| CVE-2022-50482 | 1 Linux | 1 Linux Kernel | 2026-01-23 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Clean up si_domain in the init_dmars() error path A splat from kmem_cache_destroy() was seen with a kernel prior to commit ee2653bbe89d ("iommu/vt-d: Remove domain and devinfo mempool") when there was a failure in init_dmars(), because the iommu_domain cache still had objects. While the mempool code is now gone, there still is a leak of the si_domain memory if init_dmars() fails. So clean up si_domain in the init_dmars() error path. | ||||
| CVE-2022-50481 | 1 Linux | 1 Linux Kernel | 2026-01-23 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: cxl: fix possible null-ptr-deref in cxl_guest_init_afu|adapter() If device_register() fails in cxl_register_afu|adapter(), the device is not added, device_unregister() can not be called in the error path, otherwise it will cause a null-ptr-deref because of removing not added device. As comment of device_register() says, it should use put_device() to give up the reference in the error path. So split device_unregister() into device_del() and put_device(), then goes to put dev when register fails. | ||||
| CVE-2022-50480 | 1 Linux | 1 Linux Kernel | 2026-01-23 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: memory: pl353-smc: Fix refcount leak bug in pl353_smc_probe() The break of for_each_available_child_of_node() needs a corresponding of_node_put() when the reference 'child' is not used anymore. Here we do not need to call of_node_put() in fail path as '!match' means no break. While the of_platform_device_create() will created a new reference by 'child' but it has considered the refcounting. | ||||
| CVE-2022-50478 | 1 Linux | 1 Linux Kernel | 2026-01-23 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix shift-out-of-bounds/overflow in nilfs_sb2_bad_offset() Patch series "nilfs2: fix UBSAN shift-out-of-bounds warnings on mount time". The first patch fixes a bug reported by syzbot, and the second one fixes the remaining bug of the same kind. Although they are triggered by the same super block data anomaly, I divided it into the above two because the details of the issues and how to fix it are different. Both are required to eliminate the shift-out-of-bounds issues at mount time. This patch (of 2): If the block size exponent information written in an on-disk superblock is corrupted, nilfs_sb2_bad_offset helper function can trigger shift-out-of-bounds warning followed by a kernel panic (if panic_on_warn is set): shift exponent 38983 is too large for 64-bit type 'unsigned long long' Call Trace: <TASK> __dump_stack lib/dump_stack.c:88 [inline] dump_stack_lvl+0x1b1/0x28e lib/dump_stack.c:106 ubsan_epilogue lib/ubsan.c:151 [inline] __ubsan_handle_shift_out_of_bounds+0x33d/0x3b0 lib/ubsan.c:322 nilfs_sb2_bad_offset fs/nilfs2/the_nilfs.c:449 [inline] nilfs_load_super_block+0xdf5/0xe00 fs/nilfs2/the_nilfs.c:523 init_nilfs+0xb7/0x7d0 fs/nilfs2/the_nilfs.c:577 nilfs_fill_super+0xb1/0x5d0 fs/nilfs2/super.c:1047 nilfs_mount+0x613/0x9b0 fs/nilfs2/super.c:1317 ... In addition, since nilfs_sb2_bad_offset() performs multiplication without considering the upper bound, the computation may overflow if the disk layout parameters are not normal. This fixes these issues by inserting preliminary sanity checks for those parameters and by converting the comparison from one involving multiplication and left bit-shifting to one using division and right bit-shifting. | ||||

| In the Linux kernel, the following vulnerability has been resolved: gpu: host1x: Fix memory leak of device names The device names allocated by dev_set_name() need be freed before module unloading, but they can not be freed because the kobject's refcount which was set in device_initialize() has not be decreased to 0. As comment of device_add() says, if it fails, use only put_device() drop the refcount, then the name will be freed in kobejct_cleanup(). device_del() and put_device() can be replaced with device_unregister(), so call it to unregister the added successfully devices, and just call put_device() to the not added device. Add a release() function to device to avoid null release() function WARNING in device_release(), it's empty, because the context devices are freed together in host1x_memory_context_list_free(). | ||||

| CVE-2022-50484 | 1 Linux | 1 Linux Kernel | 2026-01-23 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix potential memory leaks When the driver hits -ENOMEM at allocating a URB or a buffer, it aborts and goes to the error path that releases the all previously allocated resources. However, when -ENOMEM hits at the middle of the sync EP URB allocation loop, the partially allocated URBs might be left without released, because ep->nurbs is still zero at that point. Fix it by setting ep->nurbs at first, so that the error handler loops over the full URB list. | ||||

| In the Linux kernel, the following vulnerability has been resolved: net/tcp: Fix a NULL pointer dereference when using TCP-AO with TCP_REPAIR A NULL pointer dereference can occur in tcp_ao_finish_connect() during a connect() system call on a socket with a TCP-AO key added and TCP_REPAIR enabled. The function is called with skb being NULL and attempts to dereference it on tcp_hdr(skb)->seq without a prior skb validation. Fix this by checking if skb is NULL before dereferencing it. The commentary is taken from bpf_skops_established(), which is also called in the same flow. Unlike the function being patched, bpf_skops_established() validates the skb before dereferencing it. int main(void){ struct sockaddr_in sockaddr; struct tcp_ao_add tcp_ao; int sk; int one = 1; memset(&sockaddr,'\0',sizeof(sockaddr)); memset(&tcp_ao,'\0',sizeof(tcp_ao)); sk = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); sockaddr.sin_family = AF_INET; memcpy(tcp_ao.alg_name,"cmac(aes128)",12); memcpy(tcp_ao.key,"ABCDEFGHABCDEFGH",16); tcp_ao.keylen = 16; memcpy(&tcp_ao.addr,&sockaddr,sizeof(sockaddr)); setsockopt(sk, IPPROTO_TCP, TCP_AO_ADD_KEY, &tcp_ao, sizeof(tcp_ao)); setsockopt(sk, IPPROTO_TCP, TCP_REPAIR, &one, sizeof(one)); sockaddr.sin_family = AF_INET; sockaddr.sin_port = htobe16(123); inet_aton("127.0.0.1", &sockaddr.sin_addr); connect(sk,(struct sockaddr *)&sockaddr,sizeof(sockaddr)); return 0; } $ gcc tcp-ao-nullptr.c -o tcp-ao-nullptr -Wall $ unshare -Urn BUG: kernel NULL pointer dereference, address: 00000000000000b6 PGD 1f648d067 P4D 1f648d067 PUD 1982e8067 PMD 0 Oops: Oops: 0000 [#1] SMP NOPTI Hardware name: VMware, Inc.
