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

The following packages have been upgraded to a later upstream version: kernel (5.14.0).

Security Fix(es):

* kernel: UAF in nftables when nft_set_lookup_global triggered after handling named and anonymous sets in batch requests (CVE-2023-3390) * kernel: netfilter: nf_tables: fix chain binding transaction logic in the abort path of NFT_MSG_NEWRULE (CVE-2023-3610) * kernel: net/sched: cls_fw component can be exploited as result of failure in tcf_change_indev function (CVE-2023-3776) * kernel: netfilter: use-after-free due to improper element removal in nft_pipapo_remove() (CVE-2023-4004) * kernel: netfilter: nf_tables_newrule when adding a rule with NFTA_RULE_CHAIN_ID leads to use-after-free (CVE-2023-4147) * kernel: nf_tables: use-after-free in nft_chain_lookup_byid() (CVE-2023-31248) * kernel: nf_tables: stack-out-of-bounds-read in nft_byteorder_eval() (CVE-2023-35001) * kernel: save/restore speculative MSRs during S3 suspend/resume (CVE-2023-1637) * hw: amd: Cross-Process Information Leak (CVE-2023-20593) * kernel: bypass of shadow stack protection due to a logic error (CVE-2023-21102)

A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their privileges on the system.

ICSA-23-166-10 — Siemens SIMATIC S7-1500 TM MFP BIOS

The iconv program in the GNU C Library (aka glibc or libc6) 2.31 and earlier, when invoked with multiple suffixes in the destination encoding (TRANSLATE or IGNORE) along with the -c option, enters an infinite loop when processing invalid multi-byte input sequences, leading to a denial of service. The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-byte input sequences in the EUC-KR encoding, may have a buffer over-read. A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution. This was fixed in version 2.32. The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to sysdeps/ieee754/ldbl-96/e_rem_pio2l.c. The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance the input state, which could lead to an infinite lo…

OESA-2023-1492 — kernel security update

Affected: openEuler:22.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): An issue was discovered in the Linux kernel before 6.3.8. fs/smb/server/smb2pdu.c in ksmbd has an integer underflow and out-of-bounds read in deassemble_neg_contexts.(CVE-2023-38427) An issue was discovered in the Linux kernel before 6.3.4. fs/ksmbd/connection.c in ksmbd has an off-by-one error in memory allocation (because of ksmbd_smb2_check_message) that may lead to out-of-bounds access.(CVE-2023-38429) An issue was discovered in the Linux kernel before 6.3.9. ksmbd does not validate the SMB request protocol ID, leading to an out-of-bounds read.(CVE-2023-38430) A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their privileges on the system.(CVE-2023-4004)
