CVE-2026-74275
The CVE-2026-74275 entry is about the Linux kernel driver cxl/region where cxl_cancel_auto_attach() can access p->targets[] using a potentially negative index cxled->pos. The root cause is that cxled->pos may be set to a negative errno in cxl_region_sort_targets() if cxl_calc_interleave_...
CVE-2026-74275 cxl/region: Fix out-of-bounds access in cxl_cancel_auto_attach()
In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fix out-of-bounds access in cxlcancelautoattach In cxlcancelautoattach, it assumes cxled-pos is a valid index for accessing p-targets. However, cxled-pos can be set to negative errno in cxlregionsorttargets if...

CVE-2026-68462
Summary of CVE-2026-68462 (Linux kernel, BPF): The issue arises in the verifier’s handling of buffer-pointer access (PTR_TO_TP_BUFFER and PTR_TO_BUF) where a constant negative offset could slip through after a pointer offset split (reg->var_off vs reg->off). Specifically, an access with reg...

tar: Node-tar: Denial of Service via malformed tar archive header
A flaw was found in node-tar, a tar archive manipulation library for Node.js. A remote attacker could exploit this vulnerability by providing a specially crafted tar archive with a negative entry size in its header. This malformed header causes the archive scanner to enter an infinite loop,...
SUSE CVE-2026-67214
nanoid Nano ID before 3.3.16 and 5.1.16 contains an infinite loop in the customAlphabet and nanoid functions of its non-secure module nanoid/non-secure. When these functions are given a negative size, the loop counter is decremented from a negative value and never reaches its termination conditio...
