Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the incorrect use of kfree instead of putdevice when rioaddnet fails, which could lead to reuse after releas...

SUSE CVE-2023-53023

In the Linux kernel, the following vulnerability has been resolved: net: nfc: Fix use-after-free in localcleanup Fix a use-after-free that occurs in kfreeskb called from localcleanup. This could happen when killing nfc daemon e.g. neard after detaching an nfc device. When detaching an nfc device,...

UBUNTU-CVE-2025-21852

In the Linux kernel, the following vulnerability has been resolved: net: Add rxskb of kfreeskb to rawtpnullargs. Yan Zhai reported a BPF prog could trigger a null-ptr-deref 0 in tracekfreeskb if the prog does not check if rxsk is NULL. Commit c53795d48ee8 "net: add rxsk to tracekfreeskb" added rx...

SUSE CVE-2022-49135

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix memory leak why Resource release is needed on the error handling path to prevent memory leak. how Fix this by adding kfree on the error handling path...

SUSE CVE-2022-49256

In the Linux kernel, the following vulnerability has been resolved: watchqueue: Actually free the watch freewatch does everything barring actually freeing the watch object. Fix this by adding the missing kfree. kmemleak produces a report something like the following. Note that as an address can b...

CVE-2022-49190

In the Linux kernel, the following vulnerability has been resolved: kernel/resource: fix kfree of bootmem memory again Since commit ebff7d8f270d "mem hotunplug: fix kfree of bootmem memory", we could get a resource allocated during boot via allocresource. And it's required to release the resource...

DEBIAN-CVE-2022-49452

In the Linux kernel, the following vulnerability has been resolved: dpaa2-eth: retrieve the virtual address before dmaunmap The TSO header was DMA unmapped before the virtual address was retrieved and then used to free the buffer. This meant that we were actually removing the DMA map and then...

DEBIAN-CVE-2022-49135

CVE-2022-49627 ima: Fix potential memory leak in ima_init_crypto()

In the Linux kernel, the following vulnerability has been resolved: ima: Fix potential memory leak in imainitcrypto On failure to allocate the SHA1 tfm, IMA fails to initialize and exits without freeing the imaalgoarray. Add the missing kfree for imaalgoarray to avoid the potential memory leak...

CVE-2022-49256 watch_queue: Actually free the watch

In the Linux kernel, the following vulnerability has been resolved: watchqueue: Actually free the watch freewatch does everything barring actually freeing the watch object. Fix this by adding the missing kfree. kmemleak produces a report something like the following. Note that as an address can b...

CVE-2022-49190

CVE-2022-49190 affects the Linux kernel (kernel/resource). Root cause: boot memory allocated via alloc_resource() may be leaked if callers use kfree directly, causing a kernel BUG; remediation leaks only a few bytes to avoid patching every call site. A fix was applied in the kernel (commit ebff7d...

CVE-2022-49153

CVE-2022-49153 affects the Linux kernel via the wireguard path: when sending to a peer, skb memory is not freed if IPv6 is disabled, causing a memory leak. The root cause is missing kfree_skb() in the send6() handling within wg_socket_send_buffer_to_peer/..send_buffer_to_peer() and related code p...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: nvmet-auth: Assign dhkey to NULL after kfreesensitive. ctrl-dhkey may be used across multiple calls to nvmetsetupdhgroup for the same controller. Therefore, it’s better to set it to NULL after a error-free release, in order to...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Drivers: Soc: Xilinx: Add the missing kfree function in xlnxaddcbforsuspend. If we fail to allocate memory for cbdata using kmalloc, the memory allocation for evedata never gets freed. Therefore, add the missing kfree function in...
