The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1771332544 advisory. - When reading data from disk, the grub's UDF filesystem module utilizes the user controlled data length metadata to allocate its intern...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: udf: Avoid using corrupted block bitmap buffers. When the filesystem’s block bitmap is corrupted, we detect the corruption while loading the bitmap. As a result, allocation attempts fail with an error. However, the next allocatio...

Astra Linux – Vulnerability in Linux 5.15

A flaw in memory writing within the Linux kernel’s UDF file system functionality was discovered. This flaw allows a user to trigger certain file operations, which in turn triggers udfwritefi. A local user could exploit this flaw to crash the system or potentially cause other malicious actions...

CVE-2026-89525

This vulnerability affects the Linux kernel's UDF 1.50 virtual partition mapping in the function udf_get_pblock_virt15() . The root cause is an off-by-one bounds check : the code rejected only indexes greater than s_num_entries, but valid VAT indexes are strictly below that value. A crafted UDF i...
