SUSE CVE-2026-53215
In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: refill RX buffers before XDP or skb use The RX error path returns the current descriptor buffer to the hardware BM pool. That is only valid while the driver still owns the buffer. mvpp2rxrefill can fail after the...

CVE-2026-53215
CVE-2026-53215 affects the Linux kernel mvpp2 driver: the RX path could return a descriptor buffer to the hardware Buffer Manager after it had been handed to XDP or an skb, allowing DMA into memory no longer owned by the RX ring. Root cause is improper handling of RX buffers in mvpp2_rx_refill() ...
CVE-2026-53162 memcg: use round-robin victim selection in refill_stock
In the Linux kernel, the following vulnerability has been resolved: memcg: use round-robin victim selection in refillstock Harry Yoo reported that getrandomu32below is not safe to call in the nmi context and memcg charge draining can happen in nmi context. More specifically getrandomu32below is...
CVE-2026-53162
Summary (CVE-2026-53162) : In the Linux kernel memcg subsystem, a non-NMI-safe path around random-number generation during NMI handling could corrupt the ChaCha batch state, enabling memcg charge draining. The fix replaces the get_random_u32_below() path with a per-CPU round-robin counter stored ...

CVE-2026-43121
CVE-2026-43121 involves the Linux kernel io_uring/zcrx race between scrub and refill paths. The non-atomic read-then-decrement of the user_refs can race with io_zcrx_scrub() using atomic_xchg, causing a double-free of a niov and an out-of-bounds write past the freelist array. The fix replaces the...
