high Tenable Cloud Security Plugin ID 469917

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix slab-out-of-bounds read
 in DeleteIndexEntryRoot In the 'DeleteIndexEntryRoot' case of the 'do_action' function, the entry size
 ('esize') is retrieved from the log record without adequate bounds checking. Specifically, the code
 calculates the end of the entry ('e2') using: e2 = Add2Ptr(e1, esize); It then calculates the size for
 memmove using 'PtrOffset(e2, ...)', which subtracts the end pointer from the buffer limit. If 'esize' is
 maliciously large, 'e2' exceeds the used buffer size. This results in a negative offset which, when cast
 to size_t for memmove, interprets as a massive unsigned integer, leading to a heap buffer overflow. This
 commit adds a check to ensure that the entry size ('esize') strictly fits within the remaining used space
 of the index header before performing memory operations. (CVE-2026-45935)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19738.0.0 or later.
