  • kernel: out-of-bounds read in libiscsi module (CVE-2021-27364)

  • kernel: heap buffer overflow in the iSCSI subsystem (CVE-2021-27365)

  • kernel: iscsi: unrestricted access to sessions and handles (CVE-2021-27363)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

  • Customer testing eMMC sees and intermittent boot problem on 7.8+, was not seen on 7.3 (BZ#1918916)

  • tcm loopback driver causes double-start of scsi command when work is delayed (BZ#1925652)

  • [Azure][RHEL-7]Mellanox Patches To Prevent Kernel Hang In MLX4 (BZ#1925691)

  • A patch from upstream c365c292d059 causes us to end up leaving rt_nr_boosted in an inconsistent state, which causes a hard lockup. (BZ#1928082)

  • [RHEL7.9.z] Add fix to update snd_wl1 in bulk receiver fast path (BZ#1929804)
