ALSA-2021:4356 — Moderate: kernel security, bug fix, and enhancement update

Affected: AlmaLinux:8: kernel-tools-libs-devel

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

Security Fix(es): * kernel: out-of-bounds reads in pinctrl subsystem (CVE-2020-0427) * kernel: Improper input validation in some Intel(R) Ethernet E810 Adapter drivers (CVE-2020-24502) * kernel: Insufficient access control in some Intel(R) Ethernet E810 Adapter drivers (CVE-2020-24503) * kernel: Uncontrolled resource consumption in some Intel(R) Ethernet E810 Adapter drivers (CVE-2020-24504) * kernel: Fragmentation cache not cleared on reconnection (CVE-2020-24586) * kernel: Reassembling fragments encrypted under different keys (CVE-2020-24587) * kernel: wifi frame payload being parsed incorrectly as an L2 frame (CVE-2020-24588) * kernel: Forwarding EAPOL from unauthenticated wifi client (CVE-2020-26139) * kernel: accepting plaintext data frames in protected networks (CVE-2020-26140) * kernel: not verifying TKIP MIC of fragmented frames (CVE-2020-26141) * kernel: accepting fragmented plaintext frames in protected networks (CVE-2020-26143) * kernel: accepting unencrypted A-MSDU frames that start with RFC1042 header (CVE-2020-26144) * kernel: accepting plaintext broadcast fragments as full frames (CVE-2020-26145) * kernel: powerpc: RTAS calls can be used to compromise kernel integrity (CVE-2020-27777) * kernel: locking inconsistency in tty_io.c and tty_jobctrl.c can lead to a read-after-free (CVE-2020-29660) * kernel: buffer overflow in mwifiex_cmd_802_11_ad_hoc_start function via a long SSI…

nbd_add_socket in drivers/block/nbd.c in the Linux kernel through 5.10.12 has an ndb_queue_rq use-after-free that could be triggered by local attackers (with access to the nbd device) via an I/O request at a certain point during device setup, aka CID-b98e762e3d71.

OESA-2021-1086 — kernel security update

Affected: openEuler:20.03-LTS: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): In drivers/target/target_core_xcopy.c in the Linux kernel before 5.10.7, insufficient identifier checking in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are proxied via an attacker-selected backstore.(CVE-2020-28374) An issue was discovered in Xen through 4.14.x. Some OSes (such as Linux, FreeBSD, and NetBSD) are processing watch events using a single thread. If the events are received faster than the thread is able to handle, they will get queued. As the queue is unbounded, a guest may be able to trigger an OOM in the backend. All systems with a FreeBSD, Linux, or NetBSD (any version) dom0 are vulnerable.(CVE-2020-29568) In the nl80211_policy policy of nl80211.c, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with System execution privileges needed. User interaction is not required for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-119770583(CVE-2020-27068) A flaw was found in the Linux kernels implementation of MIDI, where an attacker with a local account and the permissions to issue an ioctl commands to midi devices, could trigger a use-afte…
