Linux Kernel Security Vulnerabilities

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 macb driver calling napiconsumeskb in a context where IRQ is disabled, resulting in a warning...

CVE-2026-31563: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net: macb: Use devconsumeskbany to free TX SKBs The napiconsumeskb function is not intended to be called in an IRQ disabled context. However, after commit 6bc8a5098bf4 "net: macb: Fix txptrlock locking", the freeing of TX SKBs is...

SUSE CVE-2026-31494

In the Linux kernel, the following vulnerability has been resolved: net: macb: use the current queue number for stats There's a potential mismatch between the memory reserved for statistics and the amount of memory written. gemgetssetcount correctly computes the number of stats based on the activ...

CVE-2026-31494

A flaw was found in the Linux kernel's macb network driver. A local user can exploit this vulnerability due to an out-of-bounds write in the gemgetethtoolstats function. This occurs when the driver incorrectly copies data using the maximum number of queues instead of the active number, leading to...
