CVE-2022-49681

The CVE-2022-49681 issue in the Linux kernel concerns xtensa: xtfpga setup where of_find_compatible_node() may return a node with an incremented refcount. The fix is to call of_node_put() when the node is no longer in use to prevent a refcount leak. Public advisories (Tencent/Unity Linux integrat...

CVE-2022-49828

CVE-2022-49828 affects the Linux kernel hugetlbfs: when a HugeTLB page is poisoned, the page was previously truncated from the page cache; the patch keeps the poisoned page in the cache. As described, subsequent reads/mappings can trigger the allocation of a new hugepage instead of signaling pois...

CVE-2023-23005

The CVE-2023-23005 issue affects the Linux kernel prior to 6.2. It occurs in mm/memory-tiers.c where alloc_memory_type is misinterpreted (treating an error pointer as NULL in the error case), potentially enabling an availability impact. The root cause is the incorrect handling of the alloc_memory...

CVE-2023-52900

CVE-2023-52900: Linux kernel nilfs2 vulnerability in nilfs_btree_insert() can cause a general protection fault when a corrupted disk image leads __nilfs_btree_get_block() to return -ENOENT. The patch changes this to -EINVAL, causing subsequent b-tree operations to report corruption and return -EI...

It affects kernel versions before 3.1, with the described impact being a denial of ...

CVE-2017-18552

CVE-2017-18552 affects the Linux kernel up to version 4.10 in net/rds/af_rds.c, where rds_recv_track_latency contains an out-of-bounds write and read. The connected Nessus advisories (Unity Linux UTSA advisories) mirror this issue and reference kernel versions before 4.11, with a commit in the Li...

CVE-2021-47224

CVE-2021-47224 concerns the Linux kernel ll_temac driver. A use-after-free can occur on the DMA side if the skb is freed while fragments are still in use because the skb pointer was piggy-backed on the first TX buffer descriptor (BD). The resolved description states the fix was to ensure the skb ...

CVE-2021-47508

CVE-2021-47508 affects the Linux kernel’s btrfs code path. The issue is a memory leak: when qgroup/data reservation fails in btrfs_check_data_free_space() or btrfs_delalloc_reserve_space(), the allocated extent_changeset is not freed. This occurs specifically in the direct IO write path (and rela...

CVE-2022-48731

The Linux kernel contains a vulnerability in the mm/kmemleak component where scanning potential huge holes can cause a soft lockup . When using devm_request_free_mem_region() and devm_memremap_pages() to add ZONE_DEVICE memory, a huge end PFN (e.g., 0x400000000) creates a massive gap between node...

CVE-2022-50202

CVE-2022-50202 maps to a Linux kernel vulnerability in the PM: hibernate flow where resuming from hibernation defers device probing. The described race involves probe_count, with wait_for_device_probe() potentially sleeping indefinitely while misc_mtx is held, due to three conditions (a device no...

CVE-2022-48795

CVE-2022-48795 maps to a PA-RISC Linux kernel issue: overrunning sglist in sba_unmap_sg caused a Data TLB miss and null-pointer dereference, leading to a kernel panic. The root cause was testing sg_dma_len(sglist) before confirming remaining entries (nents), which could cross a page boundary and ...

CVE-2022-49932

CVE-2022-49932 affects the Linux kernel KVM/vMX path where /dev/kvm is exposed before VMX initialization is complete.

CVE-2017-9984

The CVE-2017-9984 issue affects the Linux kernel’s snd_msnd_interrupt path (sound/isa/msnd/msnd_pinnacle.c) and is a local, double-fetch vulnerability that can allow over-boundary access to a message queue head pointer, potentially enabling DoS or other impact. The advisory notes vulnerable until...

CVE-2021-47195

CVE-2021-47195 relates to the Linux kernel SPI subsystem. The issue is a use-after-free caused by unlocking a per-controller mutex (add_lock) after the controller has already been freed during spi_unregister_controller(ctlr) and subsequent put_device flow. The fix moves put_device() after the mut...

CVE-2022-49937

CVE-2022-49937 affects the Linux kernel mceusb driver in the media subsystem. Automatic fuzzing reported a WARN due to an unusual read on endpoint 0 caused by using legacy usb_control_msg_() routines and not setting USB_DIR_IN in bRequestType. The fix converts the driver to usb_control_msg_recv()...

CVE-2022-49980

CVE-2022-49980 affects the Linux kernel USB gadget subsystem (udc). A race between uevent callbacks and gadget driver unregistration can cause a use-after-free in usb_udc_uevent(), when it dereferences udc->driver without holding the udc_lock mutex. If the gadget driver is unbound concurrently...

CVE-2025-39744

The CVE-2025-39744 issue affects the Linux kernel and describes a deadlock in rcu_read_unlock() when called during irq_exit() if an IPI is issued. The root cause is an incorrect handling of irq_work state inside rcu_read_unlock_special() triggered by irq_exit(), which can cause a system hang/lock...

CVE-2026-31608

CVE-2026-31608 affects the Linux kernel SMB server. The issue is a double-free in smb_direct_free_sendmsg when invoked after smb_direct_flush_send_list(); smb_direct_flush_send_list() already calls smb_direct_free_sendmsg(), so a second call after post_sendmsg() is incorrect. The fix moves the ca...

CVE-2008-3534

CVE-2008-3534 affects the Linux kernel tmpfs implementation (shmem.c: shmem_delete_inode). A local attacker could crash the system by a specific sequence of file create/remove/overwrite operations, linked to allocation of “useless pages” and improper maintenance of i_blocks. Public advisories con...

CVE-2010-4343 affects the Linux kernel, where drivers/scsi/bfa/bfa_core.c may fail to initialize a port data structure in fc_host, enabling a local user to crash the system by reading the fc_host statistics file. This is fixed in kernel versions starting with 2.6.35 (i.e., patched in 2.6.35+). Ev...

CVE-2021-47336

CVE-2021-47336 affects the Linux kernel via the smackfs path: the function smk_set_cipso() incorrectly handles a bytes-count restriction, due to a mistaken cross-check that applied only to the SMK_FIXED24_FMT path. The issue was addressed in the patch sequence starting with commit 7ef4c19d245f3dc...

CVE-2022-48845

CVE-2022-48845 affects the Linux kernel on MIPS SMP builds, where mis-timing of CPU topology map calculation caused smt_mask (cpu_smt_mask) to be empty during sched_core_cpu_starting().

CVE-2022-49982

CVE-2022-49982 affects the Linux kernel media driver pvrusb2. The leak arises from error handling in pvr2_hdw_create: the v4l2 device is not unregistered when control flow returns to pvr2_context_create, causing pvr2_hdw_destroy to exit early. The fix adds v4l2_device_unregister to decrement the ...

CVE-2023-3359

CVE-2023-3359 concerns the Linux kernel’s brcm_nvram_parse in drivers/nvmem/brcm_nvram.c, where the return value of kzalloc() is not checked, potentially causing a NULL pointer dereference.

Public sources (Red Hat, SUSE, NVD) cite impact ...

CVE-2022-49978

In the Linux kernel, CVE-2022-49978 concerns the fbdev subsystem (fb_pm2fb) where, during do_fb_ioctl() handling of FBIOPUT_VSCREENINFO, a freely copied var may propagate to fb_set_var()/fb_check_var() and reach pm2fb_check_var(). If var->pixclock is zero, the reciprocal check can trigger a di...

CVE-2022-50030

CVE-2022-50030 is a vulnerability in the Linux kernel’s lpfc driver affecting debugfs input handling. According to the provided documents, malformed user input to debugfs can cause buffer overflow crashes due to input strings not fitting internal buffers (space for NULL terminators added). The CV...

CVE-2025-38710

The CVE-2025-38710 vulnerability affects the Linux kernel GFS2: it relies on i_depth validation for exhash directories. A fuzzer introduced corruption that could yield a dir_e_read() depth of 0, causing an undefined shift by 32 at index = hash >> (32 - dip->i_depth). The minimum depth is...

CVE-2011-4611

The CVE-2011-4611 entry relates to the Linux kernel on POWERPC where an integer overflow in perf_event_interrupt (arch/powerpc/kernel/perf_event.c) before version 2.6.39 can allow a local user to trigger a denial of service via performance-event handling. Affected: Linux kernel releases prior to ...
