In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_fs: Clear ffs_eventfd in ffs_data_clear. ffs_data_clear is indirectly called from both ffs_fs_kill_sb and ffs_ep0_release, so it ends up being called twice when userland closes ep0 and then unmounts f_fs. If userland provided an eventfd along with function's USB descriptors, it ends up calling eventfd_ctx_put as many times, causing a refcount underflow. NULL-ify ffs_eventfd to prevent these extraneous eventfd_ctx_put calls. Also, set epfiles to NULL right after de-allocating it, for readability. For completeness, ffs_data_clear actually ends up being called thrice, the last call being before the whole ffs structure gets freed, so when this specific sequence happens there is a second underflow happening (but not being reported): /sys/kernel/debug/tracing# modprobe usb_f_fs /sys/kernel/debug/tracing# echo ffs_data_clear > set_ftrace_filter /sys/kernel/debug/tracing# echo function > current_tracer /sys/kernel/debug/tracing# echo 1 > tracing_on (setup gadget, run and kill function userland process, teardown gadget) /sys/kernel/debug/tracing# echo 0 > tracing_on /sys/kernel/debug/tracing# cat trace smartcard-openp-436 [000] ..... 1946.208786: ffs_data_clear <-ffs_data_closed smartcard-openp-431 [000] ..... 1946.279147: ffs_data_clear <-ffs_data_closed smartcard-openp-431 [000] .n... 1946.905512: ffs_data_clear <-ffs_data_put Warning output corresponding to above trace: [ 1946.284139] WARNING: CPU: 0 PID: 431 at lib/refcount.c:28 refcount_warn_saturate+0x110/0x15c [ 1946.293094] refcount_t: underflow; use-after-free.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6938-1 advisory.

    It was discovered that the device input subsystem in the Linux kernel did not properly handle the case     when an event code falls outside of a bitmap. A local attacker could use this to cause a denial of service     (system crash). (CVE-2022-48619)

     discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel did not     properly handle certain memory allocation failure conditions, leading to a null pointer dereference     vulnerability. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2023-46343)

    It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when     modifying certain settings values through debugfs. A privileged local attacker could use this to cause a     denial of service. (CVE-2024-24857, CVE-2024-24858, CVE-2024-24859)

    Chenyuan Yang discovered that the Unsorted Block Images (UBI) flash device volume management subsystem did     not properly validate logical eraseblock sizes in certain situations. An attacker could possibly use this     to cause a denial of service (system crash). (CVE-2024-25739)

    Use explicit argument to prevent continuation with empty cve2bugzilla file.

Therefore use the timestamp of the whole packed-ref file (better     false positive detection of update than breakage or false negative). Add unified approach to read packed-     refs regardless of KSOURCE_GIT worktree or not.
    - mass-cve: Make BRANCH mandatory
    - mass-cve: Use dedicated worktree for reference updates So that any checkout in KSOURCE_GIT is not     changed.

    - scripts/check-kernel-fix: avoid rechecking child branches when parents are OK Topological sorted     dependency tree allows to optimize check-kernel-fixe in cases where parent already has the fix. There is     not reason to check branches which merge from that branch as they will get the fix eventually.
    - scripts/check-kernel-fix: print a message when no action is needed. Script exits without printing     anything about the actions necessary in non-verbose mode. This can be confusing to a beginner user.
    - scripts/common-functions: for_each_build_branch traverse branches in dependency topo sorted list
