Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iavf: fix PTP use-after-free during reset The commit 7c01dbfc8a1c5f “iavf: periodically cache PHC time” introduced a worker that was responsible for caching PHC time. However, this worker failed to stop or disable itself during...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iavf: Fixed out-of-bounds writes in iavfgetethtoolstats. iavf incorrectly uses realnumtxqueues for ETHSSSTATS. Since this value can change during runtime, we should use numtxqueues instead. Additionally, iavfgetethtoolstats uses...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iavf: Fix for the hang during reboot/shutdown The recent commit 974578017fc1 “iavf: Add waiting so the port is initialized in remove” adds a wait-loop at the beginning of iavfremove, to ensure that port initialization is complete...

CVE-2026-43447

A flaw was found in the Linux kernel's iavf driver. A race condition exists where the Precision Time Protocol PTP worker attempts to access adapter resources that have already been freed during a reset or disable operation. This use-after-free vulnerability can lead to a system crash, resulting i...

CVE-2026-43447

Summary: CVE-2026-43447 affects the Linux kernel iavf driver. A race condition arises when a PTP worker that caches PHC time is not stopped during adapter reset/disable, potentially freeing AQ-backed resources while the worker runs. If the worker calls into ptp commands during teardown, memory/lo...

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 the issue of releasing and reusing resources during PTP reset operations in iavf, potentially...

SUSE CVE-2026-31505

In the Linux kernel, the following vulnerability has been resolved: iavf: fix out-of-bounds writes in iavfgetethtoolstats iavf incorrectly uses realnumtxqueues for ETHSSSTATS. Since the value could change in runtime, we should use numtxqueues instead. Moreover iavfgetethtoolstats uses...

CVE-2026-31505

A flaw was found in the Linux kernel's iavf driver. This vulnerability, an out-of-bounds write, occurs when a user simultaneously executes specific ethtool commands, specifically "ethtool -L" and "ethtool -S". This can lead to memory corruption, potentially causing a system crash and resulting in...

CVE-2026-31505 iavf: fix out-of-bounds writes in iavf_get_ethtool_stats()

CVE-2026-31505

The CVE-2026-31505 issue affects the Linux kernel iavf driver: out-of-bounds writes occur because iavf_get_ethtool_stats() uses real_num_tx_queues for ETH_SS_STATS while other paths use num_tx_queues, enabling memory corruption when ethtool -L and ethtool -S run concurrently. The fix is to use im...
