Summary
Important: kernel security and bug fix update
Details

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • kernel: userspace applications can misuse the KVM API to cause a write of 16 bytes at an offset up to 32 GB from vcpu->run (CVE-2021-3501)

  • kernel: nitro_enclaves stale file descriptors on failed usercopy (CVE-2021-3543)

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):

  • OVS mistakenly using local IP as tun_dst for VXLAN packets (?) (BZ#1944667)

  • Selinux: The task calling security_set_bools() deadlocks with itself when it later calls selinux_audit_rule_match(). (BZ#1945123)

  • [mlx5] tc flower mpls match options does not work (BZ#1952061)

  • mlx5: missing patches for ct.rel (BZ#1952062)

  • CT HWOL: with OVN/OVS, intermittently, load balancer hairpin TCP packets get dropped for seconds in a row (BZ#1952065)

  • [Lenovo 8.3 bug] Blackscreen after clicking on "Settings" icon from top-right corner. (BZ#1952900)

  • AlmaLinux 8.x missing uio upstream fix. (BZ#1952952)

  • Turbostat doesn't show any measured data on AMD Milan (BZ#1952987)

  • P620 no sound from front headset jack (BZ#1954545)

  • AlmaLinux kernel 8.2 and higher are affected by data corruption bug in raid1 arrays using bitmaps. (BZ#1955188)

  • [net/sched] connection failed with DNAT + SNAT by tc action ct (BZ#1956458)

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
