CVE-2022-49675

Summary (CVE-2022-49675): In the Linux kernel, the function tick_nohz_full_setup() is exported while annotated with init , which risks a use-after-free of the init text and kernel panic. The issue was detected after a section-mismatch warning from modpost and fixed by the commit 28438794aba4 (“mo...

CVE-2022-49654 net: dsa: qca8k: reset cpu port on MTU change

In the Linux kernel, the following vulnerability has been resolved: net: dsa: qca8k: reset cpu port on MTU change It was discovered that the Documentation lacks of a fundamental detail on how to correctly change the MAXFRAMESIZE of the switch. In fact if the MAXFRAMESIZE is changed while the cpu...

CVE-2022-49654

CVE-2022-49654 pertains to the Linux kernel, specifically the net: dsa: qca8k component. The issue occurs when MAX_FRAME_SIZE (MTU) is changed while the CPU port is enabled, causing the switch to panic and stop sending packets, which can render the device unreachable; a switch reset may be requir...

CVE-2022-49625

CVE-2022-49625: In the Linux kernel, the sfc driver could trigger a kernel panic when creating VFs due to a faulty buffer release path in vunmap in IRQ context. The issue stems from an IRQ/BH context restriction during DMA buffer release, with a patch that re-enables BH to safely release the buff...
