Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2024-23307)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to integer overflow in raid5_cache_count() function. A local user can trigger an integer overflow and execute arbitrary code with elevated privileges.
2) Code Injection (CVE-ID: CVE-2024-25742)
The vulnerability allows a malicious hypervisor to escalate privileges on the system.
The vulnerability exists due to improper input validation when handling interrupts. A malicious hypervisor can inject interrupt 0x80, which is used by Linux for legacy 32-bit system calls, and arbitrarily change the value stored in EAX while a SEV VM is running.
3) Error handling (CVE-ID: CVE-2024-26584)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error when handling backlogging of crypto requests in net/tls/tls_sw.c. A remote attacker can send specially crafted traffic to the system and perform a denial of service attack.
4) Race condition (CVE-ID: CVE-2024-26585)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a race condition within the tls_encrypt_done() function in net/tls/tls_sw.c. A remote attacker user can send specially crafted requests to the system and perform a denial of service (DoS) attack.
5) Improper access control (CVE-ID: CVE-2024-26642)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper access restrictions within the nf_tables_newset() function in net/netfilter/nf_tables_api.c. A local user can set arbitrary timeouts, which can result in a denial of service condition.
6) Race condition (CVE-ID: CVE-2024-26643)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within the nf_tables_unbind_set() function in net/netfilter/nf_tables_api.c. A local user can exploit the race and escalate privileges on the system.
7) Out-of-bounds read (CVE-ID: CVE-2024-26815)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to an out-of-bounds read error within the NLA_POLICY_MAX() function in net/sched/sch_taprio.c. A local user can perform a denial of service (DoS) attack.
8) Use-after-free (CVE-ID: CVE-2024-26865)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the tcp_twsk_purge() function in net/ipv4/tcp_minisocks.c. A local user can escalate privileges on the system.
9) Buffer overflow (CVE-ID: CVE-2024-26883)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the stack_map_alloc() function in kernel/bpf/stackmap.c on a 32-bit platform. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.
10) Use-after-free (CVE-ID: CVE-2024-26898)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the tx() function in drivers/block/aoe/aoenet.c, within the aoecmd_cfg_pkts() function in drivers/block/aoe/aoecmd.c. A local user can escalate privileges on the system.
11) Input validation error (CVE-ID: CVE-2024-35801)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the fpu__init_cpu_xstate() function in arch/x86/kernel/fpu/xstate.c. A local user can perform a denial of service (DoS) attack.
12) Improper error handling (CVE-ID: CVE-2024-35809)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper error handling within the pci_device_remove() function in drivers/pci/pci-driver.c. A local user can perform a denial of service (DoS) attack.
13) Input validation error (CVE-ID: CVE-2024-36031)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the __key_instantiate_and_link() function in security/keys/key.c. A local user can perform a denial of service (DoS) attack.
