In the Linux kernel, the following vulnerability has been resolved: s390/checksum: Fix csumpartial without vector facility Currently csumpartial calls csumcopy with copy=false and dst=NULL. On machines without the vector facility, csumcopy falls back to cksmdst, ..., causing the checksum to be...

CVE-2026-68356 watchdog: airoha: Prevent division by zero when clock frequency is zero

In the Linux kernel, the following vulnerability has been resolved: watchdog: airoha: Prevent division by zero when clock frequency is zero clkgetrate can return 0 when the clock provider is not properly configured or the clock is unmanaged. The driver uses wdtfreq as a divisor directly in...

CVE-2026-68356

The CVE applies to the Linux kernel watchdog driver for the Airoha clock, where clk_get_rate() can return 0 if the clock is unmanaged or misconfigured. The driver uses wdt_freq as a divisor in airoha_wdt_probe() (to compute max_timeout) and in airoha_wdt_get_timeleft() (to compute remaining time)...

CVE-2026-68355

The CVE-2026-68355 entry concerns the Linux kernel WiFi ATH11K driver. It describes a potential buffer underflow in ath11k_hal_rx_msdu_list_get() when the first msdu_details entry has a zero buffer address, causing access to msdu_details[i-1] with i == 0. The issue is mitigated by adding a separa...
