UBUNTU-CVE-2026-43372

In the Linux kernel, the following vulnerability has been resolved: net: dsa: microchip: Fix error path in PTP IRQ setup If requestthreadedirq fails during the PTP message IRQ setup, the newly created IRQ mapping is never disposed. Indeed, the kszptpirqsetup's error path only frees the mappings...

CVE-2026-43372

CVE-2026-43372 resolves a leak in the Linux kernel Microchip DSA driver during PTP IRQ setup. If request_threaded_irq() fails, the error path previously only freed mappings that had succeeded; now the kernel disposes the newly created IRQ mapping to prevent resource exhaustion. Affected component...

DSA Kernel Heap Buffer Overflow DoS

The vulnerability of the kszswitchRemove function in the drivers/net/dsa/microchip/kszcommon.c file of the DSA kernel support driver for the Linux operating system is related to the assignment of pointers. Exploiting this vulnerability could allow an attacker to cause a service failure...

Microchip driver module Heap Buffer Overflow DoS

The vulnerability of the wilcwlaninit function in the drivers/net/wireless/microchip/wilc1000/wlan.c file of the Microchip Linux kernel driver for wireless adapter support is related to unvalidated array indexing. Exploiting this vulnerability could allow an attacker to compromise the...
