Linux Distros Unpatched Vulnerability : CVE-2026-89588

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ACPI: APEI: GHES: fix ARM section length accounting after header In gheshandlearmhwerror, after skipping the cpersecprocarm header with err + 1, the remaining...

CVE-2026-80978

A flaw was found in the Linux kernel, specifically within its IP tunnel devices. A local attacker could create a stack of user-controlled IP tunnel devices, causing the system to miscalculate the required memory for network packet headers. This miscalculation can lead to unnecessary memory...

CVE-2026-89608

A flaw was found in the ecryptfs component of the Linux kernel. The ecryptfsparsepacketset function incorrectly calculates the available buffer size when processing version 1 headers, leading to an overstatement of the buffer's actual capacity. This miscalculation could allow an attacker to cause...

CVE-2026-89674

A flaw in the Linux kernel nfsd component, specifically in the nfsd4_ff_encode_layoutget() function, involves multiple errors in XDR buffer size calculations. The errors cause either an out-of-bounds write (up to 5 bytes past the reserved buffer when short strings like uid=0/gid=0 are combined wi...

CVE-2026-89608

CVE-2026-89608 affects the ecryptfs component of the Linux kernel. The function ecryptfs_parse_packet_set() calculates the remaining packet buffer size from PAGE_SIZE - 8 instead of the actual packet set buffer length, which can overstate the available buffer for version 1 headers . According to ...
