Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 461528

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: gfs2: Validate i_depth for exhash
 directories A fuzzer test introduced corruption that ends up with a depth of 0 in dir_e_read(), causing an
 undefined shift by 32 at: index = hash >> (32 - dip->i_depth); As calculated in an open-coded way in
 dir_make_exhash(), the minimum depth for an exhash directory is ilog2(sdp->sd_hash_ptrs) and 0 is invalid
 as sdp->sd_hash_ptrs is fixed as sdp->bsize / 16 at mount time. So we can avoid the undefined behaviour by
 checking for depth values lower than the minimum in gfs2_dinode_in(). Values greater than the maximum are
 already being checked for there. Also switch the calculation in dir_make_exhash() to use ilog2() to
 clarify how the depth is calculated. Tested with the syzkaller repro.c and xfstests '-g quick'.
 (CVE-2025-38710)
