Security update for the Linux Kernel (Live Patch 0 for SLE 15 SP3)

Notes

Title of the patch
Security update for the Linux Kernel (Live Patch 0 for SLE 15 SP3)
Description of the patch
This update for the Linux Kernel 5.3.18-57 fixes several issues. The following issues were fixed: - CVE-2021-3489: Fixed an issue where the eBPF RINGBUF bpf_ringbuf_reserve did not check that the allocated size was smaller than the ringbuf size (bsc#1185640). - CVE-2021-3490: Fixed an issue where the eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) did not update the 32-bit bounds (bsc#1185641). - CVE-2021-33034: Fixed a use-after-free when destroying an hci_chan. This could lead to writing an arbitrary values (bsc#1186111). - CVE-2021-32399: Fixed a race condition when removing the HCI controller (bsc#1184611). - CVE-2020-36322: Fixed an issue was discovered in FUSE filesystem implementation which could have caused a system crash (bsc#1184211). - CVE-2021-29154: Fixed incorrect computation of branch displacements, allowing arbitrary code execution (bsc#1184391). - CVE-2021-28660: Fixed an out of bounds write in rtw_wx_set_scan (bsc#1183593). - Fixed a data loss/data corruption that occurs if there is a write error on an md/raid array (bsc#1185847).

The AND/OR issues were introduced by commit 3f50f132d840 (\"bpf: Verifier, do explicit ALU32 bounds tracking\") (5.7-rc1) and the XOR variant was introduced by 2921c90d4718 (\"bpf:Fix a verifier failure with xor\") ( 5.10-rc1).",
