UBUNTU-CVE-2026-63633

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, freerdpdspdecodeopus in libfreerdp/codec/dsp.c calls StreamEnsureRemainingCapacity on context-common.buffer even though opusdecode writes decoded PCM into the caller-supplied out stream. A malicious RDP server that...

CVE-2026-72367

A flaw was found in the Linux kernel's iomap subsystem. This vulnerability occurs due to an integer underflow when calculating iosize during concurrent file truncation operations. If a file is truncated while writeback is in progress, the iosize can wrap to a large value, leading to incorrect...

CVE-2026-65610

nnn stores homelen variable as uchart, which can only represent values in the range 0-255. An attacker who can influence the victim's execution environment can provide an arbitrary HOME path with length that is truncated to 0. The expression homelen - 1 is promoted to signed int and becomes -1 an...
