CVE-2026-59090

A flaw was found in GIMP's PSD file format plugin. This vulnerability, an unsigned integer underflow in the blockrem variable, occurs when a user opens a specially crafted .psd image file. The underflow leads to parser confusion, enabling an attacker to inject arbitrary data as layer resource...

CVE-2026-68355

The CVE-2026-68355 entry concerns the Linux kernel WiFi ATH11K driver. It describes a potential buffer underflow in ath11k_hal_rx_msdu_list_get() when the first msdu_details entry has a zero buffer address, causing access to msdu_details[i-1] with i == 0. The issue is mitigated by adding a separa...
