| Title: | Security update for the Linux Kernel (Important) |
| Description: |
The SUSE Linux Enterprise 15 SP2 Azure kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- Unprivileged BPF has been disabled by default to reduce attack surface as too many security issues have happened in the past (jsc#SLE-22573)
You can reenable via systemctl setting /proc/sys/kernel/unprivileged_bpf_disabled to 0. (kernel.unprivileged_bpf_disabled = 0)
- CVE-2021-0941: In bpf_skb_change_head of filter.c, there is a possible out of bounds read due to a use after free. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1192045). - CVE-2021-31916: An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module in the Linux kernel A bound check failure allowed an attacker with special user (CAP_SYS_ADMIN) privilege 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 (bnc#1192781). - CVE-2021-20322: Make the ipv4 and ipv6 ICMP exception caches less predictive to avoid information leaks about UDP ports in use. (bsc#1191790) - CVE-2021-34981: Fixed file refcounting in cmtp when cmtp_attach_device fails (bsc#1191961). - CVE-2021-43389: There was an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c (bnc#1191958). - CVE-2021-37159: hso_free_net_device in drivers/net/usb/hso.c called unregister_netdev without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free (bnc#1188601).
