AZL-100968 CVE-2026-19542 affecting package glibc 2.38-21

Calling tdelete on a sufficiently deep tree in the GNU C Library version 2.1 to 2.44 may write one pointer past the end of an alloca-allocated array on the stack, which may crash the application. The tdelete implementation keeps an explicit stack of parent nodes for rebalancing, which is grown as...

CVE-2026-19542

CVE-2026-19542 is a stack-based out-of-bounds write in the tdelete function of the GNU C Library (glibc) versions 2.1 through 2.44. The root cause is that two rebalancing branches in tdelete push an entry onto an alloca-allocated parent-node stack without checking capacity, writing one pointer pa...

glibc: Fix out-of-bounds array write in tdelete

A flaw was found in glibc. An out-of-bounds array write vulnerability exists within the tdelete function. This issue occurs due to incorrect management of array sizes, which can lead to memory corruption. A local attacker with low privileges could potentially exploit this to cause a denial of...
