Echo: linux: security update to 6.1.180-1

high Tenable Self-Hosted Container Security Plugin ID 461780

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: exfat: bound uniname advance in
exfat_find_dir_entry() In exfat_find_dir_entry(), each TYPE_EXTEND (file name) entry advances the output
pointer by a fixed amount while the loop guard only tracks the accumulated name length: if (++order == 2)
uniname = p_uniname->name; else uniname += EXFAT_FILE_NAME_LEN; len = exfat_extract_uni_name(ep,
entry_uniname); name_len += len; unichar = *(uniname+len); *(uniname+len) = 0x0; uniname grows by
EXFAT_FILE_NAME_LEN (15) per name entry, but name_len grows only by the actual extracted length, which is
shorter when a name fragment contains an early NUL. The only guard is `name_len >= MAX_NAME_LENGTH`, so a
crafted directory with many short name fragments lets uniname run far past the
p_uniname->name[MAX_NAME_LENGTH + 3] buffer while name_len stays small, causing an out-of-bounds read and
write at *(uniname+len). The sibling extractor exfat_get_uniname_from_ext_entry() already stops on a short
fragment (the lockstep `len != EXFAT_FILE_NAME_LEN` guard added in commit d42334578eba ("exfat: check if
filename entries exceeds max filename length")); exfat_find_dir_entry() never got the equivalent. Track
the per-entry write offset as a count and reject a fragment once the offset, or the offset plus the
extracted length, would exceed MAX_NAME_LENGTH, before forming the output pointer. (CVE-2026-64296)

Solution

Update the linux library and its related packages to version 6.1.180-1 or later.
