CVE-2026-68165

The CVE affects the Linux kernel DAMON subsystem (mm/damon/core) where damon_set_regions() did not validate zero-length regions created by certain callers (DAMON_SYSFS, DAMON_RECLAIM, DAMON_LRU_SORT). This could trigger WARN_ONCE on CONFIG_DAMON_DEBUG_SANITY and cause a divide-by-zero in damon_me...

CVE-2026-68145

CVE-2026-68145 describes a Linux kernel iomap vulnerability where zero-length ranges in ifs_set_range_dirty() and ifs_set_range_uptodate() cause an unsigned underflow in (off + len - 1) >> i_blkbits, producing a huge last_blk and nr_blks and leading to out-of-bounds bitmap_set() writes. A f...

CVE-2026-68124

CVE-2026-68124 affects the Linux kernel MCTP serial driver. A zero-length frame could cause an out-of-bounds write in the receive path when rxlen == 0, requiring CAP_NET_ADMIN to attach the MCTP line discipline and bring up the netdev. The fix routes zero-length frames to STATE_TRAILER (instead o...

Astra Linux – Vulnerability in libsoup2.4

A flaw was discovered in libsoup. An integer underflow vulnerability occurs when processing content with a zero-length resource, resulting in a buffer overread. This can allow an attacker to potentially access sensitive information or cause a denial of service at the application level...

Astra Linux – Vulnerability in libssh

A flaw was discovered in libssh. The API function sshgethexa is vulnerable to a denial-of-service attack when processing zero-length inputs. This vulnerability can be exploited remotely by an attacker during GSSAPI Generic Security Service Application Program Interface authentication, if the...
