Security update for the Linux Kernel (important)






An update that solves 22 vulnerabilities and has 22 fixes
is now available.


The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various
security and bugfixes.

The following security bugs were fixed:

  • CVE-2022-25636: Fixed an issue which allowed a local users to gain
    privileges because of a heap out-of-bounds write in nf_dup_netdev.c,
    related to nf_tables_offload (bsc#1196299).
  • CVE-2022-26490: Fixed a buffer overflow in the st21nfca driver. An
    attacker with adjacent NFC access could trigger crash the system or
    corrupt system memory (bsc#1196830).
  • CVE-2022-0487: A use-after-free vulnerability was found in
    rtsx_usb_ms_drv_remove() in drivers/memstick/host/rtsx_usb_ms.c
  • CVE-2022-24448: Fixed an issue if an application sets the O_DIRECTORY
    flag, and tries to open a regular file, nfs_atomic_open() performs a
    regular lookup. If a regular file is found, ENOTDIR should have occured,
    but the server instead returned uninitialized data in the file
    descriptor (bsc#1195612).
  • CVE-2022-0617: Fixed a null pointer dereference in UDF file system
    functionality. A local user could crash the system by triggering
    udf_file_write_iter() via a malicious UDF image. (bsc#1196079)
  • CVE-2022-0644: Fixed a denial of service by a local user. A assertion
    failure could be triggered in kernel_read_file_from_fd(). (bsc#1196155)
  • CVE-2022-25258: The USB Gadget subsystem lacked certain validation of
    interface OS descriptor requests, which could have lead to memory
    corruption (bsc#1196096).
  • CVE-2022-24958: drivers/usb/gadget/legacy/inode.c mishandled dev->buf
    release (bsc#1195905).
  • CVE-2022-24959: Fixed a memory leak in yam_siocdevprivate() in
    drivers/net/hamradio/yam.c (bsc#1195897).
  • CVE-2021-44879: In gc_data_segment() in fs/f2fs/gc.c, special files were
    not considered, which lead to a move_data_page NULL pointer dereference
  • CVE-2021-0920: Fixed a local privilege escalation due to a
    use-after-free vulnerability in unix_scm_to_skb of af_unix (bsc#1193731).
  • CVE-2021-39657: Fixed an information leak in the Universal Flash Storage
    subsystem (bsc#1193864).
  • CVE-2022-26966: Fixed an issue in drivers/net/usb/sr9700.c, which
    allowed attackers to obtain sensitive information from heap memory via
    crafted frame lengths from a device (bsc#1196836).
  • CVE-2021-39698: Fixed a possible memory corruption due to a use after
    free in aio_poll_complete_work. This could lead to local escalation of
    privilege with no additional execution privileges needed. (bsc#1196956)
  • CVE-2021-45402: The check_alu_op function in kernel/bpf/verifier.c did
    not properly update bounds while handling the mov32 instruction, which
    allowed local users to obtain potentially sensitive address information

CVE-2022-23041,CVE-2022-23042: Fixed multiple issues which could have
lead to read/write access to memory pages or denial of service. These
issues are related to the Xen PV device frontend drivers. (bsc#1196488)

    include sourcedir in certificate path.”)
  • kernel-binary.spec: Do not use the default certificate path
    (bsc#1194943). Using the the default path is broken since Linux 5.17
  • kernel-binary: Do not include sourcedir in certificate path. The certs
    macro runs before build directory is set up so it creates the aggregate
    of supplied certificates in the source directory. Using this file
    directly as the certificate in kernel config works but embeds the source
    directory path in the kernel config. To avoid this symlink the
    certificate to the build directory and use relative path to refer to it.
    Also fabricate a certificate in the same location in build directory
    when none is provided.
