The remote AlmaLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2023:2148 advisory.

  - Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result     in data leakage. (CVE-2021-26341)

  - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of     bounds. (CVE-2021-33655)

  - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462)

  - With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID     is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.
    (CVE-2022-1789)

  - A use-after-free flaw was found in the Linux kernel's pipes functionality in how a user performs     manipulations with the pipe post_one_notification() after free_pipe_info() that is already called. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1882)

  - In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking.

  - An issue was discovered in the Linux kernel before 5.19.16. Attackers able to inject WLAN frames could     cause a buffer overflow in the ieee80211_bss_info_update function in net/mac80211/scan.c. (CVE-2022-41674)

  - mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse.
    (CVE-2022-42703)

  - Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel 5.1 through     5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to trigger use-after-     free conditions to potentially execute code. (CVE-2022-42720)

  - A list management bug in BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before     5.19.16 could be used by local attackers (able to inject WLAN frames) to corrupt a linked list and, in     turn, potentially execute code. (CVE-2022-42721)

  - In the Linux kernel 5.8 through 5.19.x before 5.19.16, local attackers able to inject WLAN frames into the     mac80211 stack could cause a NULL pointer dereference denial-of-service attack against the beacon     protection of P2P devices. (CVE-2022-42722)

  - There are use-after-free vulnerabilities in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_connect     and l2cap_le_connect_req functions which may allow code execution and leaking kernel memory (respectively)     remotely via Bluetooth. A remote attacker could execute code leaking kernel memory via Bluetooth if within     proximity of the victim. We recommend upgrading past commit https://www.google.com/url     https://github.com/torvalds/linux/commit/711f8c3fb3db61897080468586b970c87c61d9e4     https://www.google.com/url (CVE-2022-42896)

  - drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-     space client to corrupt the monitor's internal memory. (CVE-2022-43750)

  - In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows     an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control     configuration that is set up with tc qdisc and tc class commands. This affects qdisc_graft in     net/sched/sch_api.c. (CVE-2022-47929)

  - A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

  - There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a     use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can     install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this     socket is disconnected and reused as a listener. If a new socket is created from the listener, the context     is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend     upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)

  - A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race     problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 (net: sched: fix race     condition in qdisc_graft()) not applied yet, then kernel could be affected. (CVE-2023-0590)

  - A data race flaw was found in the Linux kernel, between where con is allocated and con->sock is set. This     issue leads to a NULL pointer dereference when accessing con->sock->sk in net/tipc/topsrv.c in the tipc     protocol in the Linux kernel. (CVE-2023-1382)

  - AMD recommends using a software mitigation for this issue, which the kernel is enabling by default. The     Linux kernel will use the generic retpoline software mitigation, instead of the specialized AMD one, on     AMD instances (*5a*). This is done by default, and no administrator action is needed. (CVE-2021-26341)     (CVE-2022-21505)
