In the Linux kernel, the following vulnerability has been resolved: i2c: tegra: fix pmruntime leak on mutexlock failure If tegrai2cmutexlock fails, the function returns without calling pmruntimeput, leaking the runtime PM reference acquired by the preceding pmruntimegetsync. This prevents the...

CVE-2026-64154

The flaw is in the Linux kernel's Adreno GPU driver (a6xx_gpu_init), where of_parse_phandle() acquires a device node reference that early error returns fail to release via of_node_put(), causing resource accumulation. The fix uses __free(device_node) for automatic cleanup. Red Hat notes it is not...

In the Linux kernel, the following vulnerability has been resolved: ipv6: ioam: refresh hdr pointer before ioam6event Reported by Sashiko: In ipv6hopioam, the hdr pointer is initialized to point into the skb's linear data buffer. Later, the code calls skbensurewritable, which might reallocate the...

CVE-2026-64122

In the Linux kernel, CVE-2026-64122 affects the mlx5e driver (net/mlx5e). The vulnerability is a use-after-free in mlx5e_tx_reporter_timeout_recover, where sq->netdev is accessed after mlx5e_safe_reopen_channels() tears down the channel and its embedded SQs. The fix replaces three sq->netde...
