CVE-2026-74550

Summary: CVE-2026-74550 affects the Linux kernel’s redirect handling for ICMP/NDISC redirects when peer allocation fails. When inet_getpeer_v4() or inet_getpeer_v6() cannot allocate a peer entry under memory pressure or tree size caps, redirect handlers previously could emit un-rate-limited ICMP/...

In the Linux kernel, the following vulnerability has been resolved: i2c: jz4780: Cache host clock rate at probe to prevent CCF preparelock deadlock Fix a severe AB/BA deadlock between the Common Clock Framework CCF and the I2C adapter lock, which triggers when an I2C-controlled clock generator...

CVE-2026-74463

The CVE-2026-74463 issue concerns the Linux kernel: i2c: jz4780: Cache host clock rate at probe to prevent CCF prepare_lock deadlock. The root cause is that during an I2C clock frequency change, the Common Clock Framework (CCF) can deadlock with the I2C adapter lock when clk_get_rate() is invoked...

CVE-2026-72326

CVE-2026-72326 affects the Linux kernel’s net/sched cake scheduler. CAKE accepts signed overhead values stored in an s16, but the adjusted packet length calculation uses unsigned arithmetic, allowing a negative effective length to wrap to a large value. This can cause rate accounting to depend on...

CVE-2026-72238

CVE-2026-72238 affects the Linux kernel in the x86/boot path, where an empty/0/invalid baud rate for uart8250 could lead to a division by zero in early_serial_init() and cause a hang during early boot. The documented fix is to fall back to DEFAULT_BAUD when the computed baud rate is 0. The connec...
