PT-2026-44350

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free or type confusion issue exists in the SCTP implementation of the Linux kernel. In the sctp sendmsg function, the SCTP SENDALL path iterates through associations using li...

CVE-2026-45937

The CVE-2026-45937 entry concerns the Linux kernel crypto driver inside-secure/eip93. During driver detach, a programming error unregisters the same hash algorithm multiple times due to a faulty iterator, leading to a kernel panic. The vulnerability affects the kernel code path handling driver de...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from an iterator error during driver separation in the crypto/inside-secure/eip93 module. This error...

PT-2026-43804

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A kernel panic can occur during driver detach in the inside-secure/eip93 crypto component. This happens because a wrong iterator causes the same hash algorithm to be unregistered multipl...

CVE-2026-43494

In the Linux kernel, the following vulnerability has been resolved: net/rds: reset opnents when zerocopy page pin fails When iovitergetpages2 fails in rdsmessagezcopyfromuser, the pinned pages are released with putpage, and rm-data.opmmpznotifier is cleared. But we fail to properly clear...

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: clk: imx: scu: use safe list iterator to avoid a use after free This loop is freeing the variable “clk”, so it needs to use listforeachentrysafe. Otherwise, it will dereference a freed variable to obtain the next item in the loop...

Astra Linux – Vulnerability in Firefox

A stop condition for the iterator was missing when handling WASM code in the built-in profiler, potentially leading to invalid memory access and undefined behavior. Note: This issue only affects the application when the profiler is running. This vulnerability affects Firefox versions less than 12...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: drbd: Use of “free” after calling drbdcreatedevice The drbdDestroyConnection function frees the “connection” object. Therefore, it is necessary to use the safe iterator to prevent a use of a freed resource after the initial...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Regulator: Core – Prevent integer underflow By using a ratio of delay to pollEnabledTime that is not an integer, timeRemaining underflows may occur, causing the loop not to exit as expected. Since delay can be derived from DT, an...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: netfs: Fixed a kernel bug in netfslimititer, specifically for ITERKVEC iterators. When a process crashes and the kernel writes a core dump to a 9P filesystem, kernelwrite creates an ITERKVEC iterator. This iterator calls...
