CVE-2021-3743

An out-of-bounds (OOB) memory read flaw was found in the Qualcomm IPC router protocol in the Linux kernel. A missing sanity check allows a local attacker to gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability.

An out-of-bounds (OOB) memory read flaw was found in the Qualcomm IPC router protocol in the Linux kernel. A missing sanity check allows a local attacker to gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability.

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

This kernel update is based on upstream 5.10.62 and fixes at least the following security issues:

A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system (CVE-2021-3640).

A process with CAP_SYS_ADMIN can cause a kernel NULL pointer dereference in btrfs code (CVE-2021-3739).

there is an out-of-bound read bug in qrtr_endpoint_post in net/qrtr/qrtr.c (CVE-2021-3743).

An out-of-bounds read due to a race condition has been found in the Linux kernel due to write access to vc_mode is not protected by a lock in vt_ioctl (KDSETMDE) (CVE-2021-3753).

A race condition was discovered in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in the Linux kernel through 5.13.13 (CVE-2021-40490).

Other fixes in this update:

• audio stopped working with the update to kernel 5.10.60 released in MGASA-2021-0409 (mga#29426).
• x86/ACPI/State: Optimize C3 entry on AMD CPUs
• fscrypt: add fscrypt_symlink_getattr() for computing st_size
• ext4: report correct st_size for encrypted symlinks
• f2fs: report correct st_size for encrypted symlinks
• ubifs: report correct st_size for encrypted symlinks

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

The following security bugs were fixed:

• CVE-2021-3640: Fixed a Use-After-Free vulnerability in function sco_sock_sendmsg() in the bluetooth stack (bsc#1188172).
