CVE-2026-80924

A flaw was found in the Linux kernel's Kerberos 5 krb5 cryptography module. When handling derived key buffers, the cryptokrb5prepareencryption and cryptokrb5preparechecksum functions incorrectly use kfree instead of kfreesensitive for memory deallocation. This oversight leaves sensitive key...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: hdlcppp: Synchronization of per-protocol timers before freeing the hdlc state Each PPP control protocol LCP/IPCP/IPV6CP embedded in struct ppp registers a timer via timersetup. This struct ppp represents the hdlc-state allocation...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: cpuidle: dtidlegenpd: kfree is used for the original name allocation. dtidlepdalloc uses kasprintf to retrieve the full node path, then points pd-name to the basename of that string obtained by kbasename. dtidlepdfree also uses...

In the Linux kernel, the following vulnerability has been resolved: s390/ctcm: Fixed double-kfree issue. The function ‘mpcrcvdsweepreqmpcginfo’ is called conditionally from the function ‘ctcmpcunpackskb’. It frees the passed mpcginfo. After that, a call to the function ‘kfree’ within the function...

CVE-2026-90104

A flaw was found in the Linux kernel's NFSv4.1 implementation. When decoding callback sequence arguments, an uninitialized pointer in the referringcalllist can be passed to the kfree function. This memory corruption vulnerability could allow a remote attacker to cause a denial of service by...

PT-2026-106509

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free flaw exists in the drm/msm component. The msm ringbuffer destroy and msm gem vm free functions use kfree to release objects containing a drm gpu scheduler structure...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: Thermal: int340x: fixed a memory leak in int3400notify The following memory leaks are likely to occur on my TigerLake platform: Unreferenced object: 0xffff927c8b91dbc0 size 32 Details: comm “kworker/0:2”, pid 112, jiffies...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ima: Fixed a potential memory leak in imainitcrypto. If the SHA1 format is not successfully allocated, IMA fails to initialize and exits without freeing the imaalgoarray. Adding the necessary kfree call for imaalgoarray will...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fixed memory leak. Why Resource release is necessary on the error handling path to prevent memory leaks. How This issue was fixed by adding the kfree function to the error handling path...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel up to version 6.2.7, fs/ntfs3/inode.c contains an invalid kfree function because it does not validate the MFT flags before replaying logs...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bpf, s390: Fixed a potential memory leak related to jitdata. Make sure that jitdata is freed through kfree in the error path...

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 memory allocation for cbdata fails using kmalloc, the memory allocation for evedata never gets freed. Therefore, add the missing kfree function in th...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: soc: aspeed: socinfo: Added kfree call for kstrdup. Added kfree in the subsequent error handling to avoid memory leaks...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: rapidio: Replace riofreenet with kfree in rioscanallocnet. When the idtab allocation fails, the network is not yet registered with rioaddnet. Therefore, calling kfreenet is sufficient to release the memory. Set mport-net to NULL ...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: afunix: Calling kfreeskb for dead unixsk-oobskb in GC. syzbot reported a warning in unixgc, which creates a socketpair and sends the fd of one socket to itself using the peer. socketpairAFUNIX, SOCKSTREAM, 0, 3, 4 = 0 sendmsg4,...
