CVE-2026-64498

The CVE-2026-64498 issue affects the Linux kernel IIO subsystem (iio: buffer: hw-consumer). The root cause was a lifetime change for scan_mask: it moved to a separate bitmap allocation (buffer.scan_mask) but iio_hw_buf_release() remained unchanged, risking improper cleanup. The fix ensures the sc...

CVE-2026-63808

CVE-2026-63808 (Linux kernel exFAT): The vulnerability is a potential use-after-free in exfat_find_dir_entry() where a buffer_head is freed before all reads on the TYPE_EXTEND path, leading to a read from invalid memory. The root cause is brelse(bh) occurring before ep is no longer dereferenced; ...

kernel: gfs2: Fix use-after-free in iomap inline data write path

A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...

CVE-2026-40211

An attacker can send crafted DNS over HTTP/3 queries, triggering an exception that prevents some buffer from being freed right away. The buffer will be freed at the end of the QUIC connection, but on some setups it might be possible to open enough concurrent DoH3 streams to trigger an out-of-memo...
