In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: Rework long task execution when adding/deleting entries When adding/deleting large number of elements in one step in ipset, it can take a reasonable amount of time and can result in soft lockup errors. The patch 5f7b51bf09ba ("netfilter: ipset: Limit the maximal range of consecutive elements to add/delete") tried to fix it by limiting the max elements to process at all. However it was not enough, it is still possible that we get hung tasks. Lowering the limit is not reasonable, so the approach in this patch is as follows: rely on the method used at resizing sets and save the state when we reach a smaller internal batch limit, unlock/lock and proceed from the saved state. Thus we can avoid long continuous tasks and at the same time removed the limit to add/delete large number of elements in one step. The nfnl mutex is held during the whole operation which prevents one to issue other ipset commands in parallel.

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1781347338 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: net: mdio: unexport __init-annotated     mdio_bus_init() EXPORT_SYMBOL and __init is a bad combination because the .init.text section is freed up     after the initialization. Hence, modules cannot use symbols annotated __init. The access to a freed symbol     may end up with kernel panic. modpost used to detect it, but it has been broken for a decade. Recently, I     fixed modpost so it started to warn it again, then this showed up in linux-next builds. There are two ways     to fix it: - Remove __init - Remove EXPORT_SYMBOL I chose the latter for this case because the only in-     tree call-site, drivers/net/phy/phy_device.c is never compiled as modular. (CONFIG_PHYLIB is boolean)     (CVE-2022-49350)

  - In the Linux kernel, the following vulnerability has been resolved: selinux: fix memleak in     security_read_state_kernel() In this function, it directly returns the result of __security_read_policy     without freeing the allocated memory in *data, cause memory leak issue, so free the memory if
    __security_read_policy failed. [PM: subject line tweak] (CVE-2022-50201)

  - In the Linux kernel, the following vulnerability has been resolved: usb: typec: tcpci: fix of node     refcount leak in tcpci_register_port() I got the following report while doing device(mt6370-tcpc) load     test with CONFIG_OF_UNITTEST and CONFIG_OF_DYNAMIC enabled: OF: ERROR: memory leak, expected refcount 1     instead of 2, of_node_get()/of_node_put() unbalanced - destroy cset entry: attach overlay node     /i2c/pmic@34/tcpc/connector The 'fwnode' set in tcpci_parse_config() which is called in     tcpci_register_port(), its node refcount is increased in device_get_named_child_node(). It needs be put     while exiting, so call fwnode_handle_put() in the error path of tcpci_register_port() and in     tcpci_unregister_port() to avoid leak. (CVE-2022-50246)

  - In the Linux kernel, the following vulnerability has been resolved: drivers: serial: jsm: fix some leaks     in probe This error path needs to unwind instead of just returning directly. (CVE-2022-50312)

  - In the Linux kernel, the following vulnerability has been resolved: thermal: intel_powerclamp: Use     get_cpu() instead of smp_processor_id() to avoid crash When CPU 0 is offline and intel_powerclamp is used     to inject idle, it generates kernel BUG: BUG: using smp_processor_id() in preemptible [00000000] code:

Here CPU 0     is the control CPU by default and changed to the current CPU, if CPU 0 offlined. This check has to be     performed under cpus_read_lock(), hence the above warning. Use get_cpu() instead of smp_processor_id() to     avoid this BUG. [ rjw: Subject edits ] (CVE-2022-50494)

    In the Linux kernel, the following vulnerability has been resolved:

    dm integrity: Fix UAF in dm_integrity_dtr() (CVE-2022-50889)

    The Linux kernel does not correctly mitigate SMT attacks, as discovered through a strange pattern in the     kernel API using STIBP as a mitigation, leaving the process exposed for a short period of time after a     syscall. The kernel also does not issue an IBPB immediately during the syscall. (CVE-2023-0045)

    A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could     allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to     the root user via arbitrary code execution. (CVE-2023-0179)

    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)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0459)

    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)

    cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

    atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition     rather than valid classification results). (CVE-2023-23455)

    In the Linux kernel 6.0.8, there is a use-after-free in run_unpack in fs/ntfs3/run.c, related to a     difference between NTFS sector size and media sector size. (CVE-2023-26544)
