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: preserve ACL_DONT_CACHE state in
forget_cached_acl() The ACL_DONT_CACHE state is meant to be a constant state for the inode for filesystems
that want to opt out of posix acl caching. Commit facd61053cff1 ("fuse: fixes after adapting to new posix
acl api") used this facility to opt out of posix acl caching for fuse inodes with fuse server that does
not negotiate FUSE_POSIX_ACL (fc->posix_acl). The commit also takes care to gate the
forget_all_cached_acls() call in fuse_set_acl() on fc->posix_acl because there is no need for it, but
there are other placed in fuse code which call forget_all_cached_acls() unconditional to fc->posix_acl and
those cause the loss of the ACL_DONT_CACHE state. This is not only a functional bug. Properly timed, a
get_acl() from this fuse filesystem can return a stale cached value, as was observed in tests, because
set_acl() does not invalidate the unintentional acl cache. We could fix this in fuse, but it actually
makes no sense for the vfs helper forget_cached_acl() to invalidate the ACL_DONT_CACHE state, so let it
not do that to fix fuse and future users of ACL_DONT_CACHE. (CVE-2026-68149)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.675.64 or later.
