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 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: udf: Do not bother merging very long extents. When merging very long extents, we try to assign as much length as possible to the first extent. However, this is unnecessarily complicated and not really worth the effort. Moreover,...

In the Linux kernel, the following vulnerabilities have been resolved: udf: Fixed a slab-out-of-bounds write bug in udffindentry Syzbot reported a slab-out-of-bounds Write bug: loop0: A capacity change from 0 to 2048 was detected. ==================================================================...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: udf: Fixed NULL pointer dereferencing in the udfsymlink function. In the udfsymlink function, epos.bh is assigned the value returned by udftgetblk. The udftgetblk function is defined in udf/misc.c and returns the value of the...

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

In the Linux kernel, the following vulnerabilities have been resolved: udf: Avoid excessive partition sizes. Avoid mounting file systems where the partition would overflow the 32-bit range used for block numbers. Also, refuse to mount file systems where the partition size is so large that it is...

Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw involving a null pointer dereference was discovered in the Linux kernel’s UDF file system functionality. This flaw allows a malicious UDF image to trigger the udffilewriteiter function. A local user could exploit this flaw to crash the system. The flaw is present in the Linux kernel versio...

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...

SUSE CVE-2026-89525

In the Linux kernel, the following vulnerability has been resolved: udf: reject VAT indexes equal to the entry count UDF 1.50 virtual partition mapping uses the VAT as an array of physical block mappings. snumentries stores the number of entries in that array, not the highest valid index. The val...

Linux Distros Unpatched Vulnerability : CVE-2026-89525

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - udf: reject VAT indexes equal to the entry count UDF 1.50 virtual partition mapping uses the VAT as an array of physical block mappings. snumentries stores the...

CVE-2026-89525

A flaw was found in the Linux kernel. A local attacker could craft a malicious Universal Disk Format UDF image to trigger an out-of-bounds read vulnerability in the udfgetpblockvirt15 function. This occurs when the system attempts to read a Virtual Allocation Table VAT index equal to the entry...

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...
