CVE-2026-74592

A flaw was found in the Linux kernel's Integrity Measurement Architecture IMA. When a file is truncated, the system's integrity policy hooks are not properly instantiated, preventing the action cache flags from being reset. This oversight means that after truncation, the file is not re-collected,...

CVE-2026-74671

A flaw was found in the Linux kernel's Integrity Measurement Architecture IMA subsystem. The xattrverify function, which verifies extended attributes, incorrectly mixes int and sizet data types in its digest-length check. This can lead to an integer underflow when processing a truncated extended...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: x86/kexec: added a sanity check on the previous kernel’s ima kexec buffer. When the second-stage kernel is booted via kexec with a limiting command line such as “mem=”, the physical range that contains the carried over IMA...

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: ima: Handle error codes returned by imafilterrulematch. In imamatchrules, if imafilterrulematch returns -ENOENT due to the rule being NULL, the function incorrectly skips the 'if !rc' check and sets 'result = true'. The LSM rule ...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, if the IMA appraisal method is used with the “imaappraiselog” boot parameter, lockdown can be circumvented using kexec on any machine when Secure Boot is disabled or unavailable. IMA prevents the “imaappraiselog” parameter from being set during boot, but this does not cover...

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 template is unable to be allocated, IMA fails to initialize and exits without freeing the imaalgoarray. Adding the necessary kfree call for imaalgoarray will preven...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: The imagetkexecbuffer function does not check whether the ima-kexec-buffer of the previous kernel lies outside the addressable memory range. This can lead to a kernel panic if the new kernel is booted with the mem=X argument, and...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ima: Fixed a potential integer overflow in imaappraisemeasurement. When ima-modsig is enabled, the rc parameter passed to evmverifyxattr may be negative, which could lead to an integer overflow issue...

Astra Linux – Vulnerability in libsdl2

In SDL Simple DirectMediaLayer versions 2.x through 2.0.9, there is a heap-based buffer over-read issue in the FillIMAADPCMblock function, caused by an integer overflow in the IMAADPCMDecode function in the audio/SDLwave.c file...

SUSE CVE-2026-74592

In the Linux kernel, the following vulnerability has been resolved: ima: Instantiate filetruncate and pathtruncate hooks Instantiate the filetruncate and pathtruncate LSM hooks to reset the action cache flags IMADONEMASK as soon as truncation is requested, so the file, based on policy, is...

CVE-2026-74671

In the Linux kernel, the following vulnerability has been resolved: ima: fix out-of-bounds read in xattrverify The digest-length check in xattrverify mixes int and sizet: if xattrlen - sizeofxattrvalue-type - hashstart = iint-imahash-length sizeof yields sizet, so the usual arithmetic conversions...

CVE-2026-74671

CVE-2026-74671 is an out-of-bounds read in the Linux kernel's IMA (Integrity Measurement Architecture) subsystem, specifically in the xattr_verify() function. The root cause is a type mismatch between int and size_t in the digest-length check: sizeof() promotes the entire left-hand expression to ...
