    The following non security issues were fixed:

    - Add the git commit and branch to the package description (bsc#920633)
    - Fix description in rpm spec file Spec file description mentions initial kGraft patch which is only true     for real initial patch. Make it more neutral. (bsc#930408)
    - Mark the module as supported (bsc#904970)
    - Provide common kallsyms wrapper API With bsc#1103203, the need for disambiguating between a multiply     defined symbol arose. This is something the kallsyms_lookup_name() based code snippet we used to     copy&paste to every individual CVE fix can't handle. Implement a proper wrapper API for doing the kallsyms     lookups.
    - Require exact kernel version in the patch (bsc#920615)
    - Revert 'Require exact kernel version in the patch' This needs to be done differently, so that modprobe
    --force works as expected. (bsc#920615) This reverts commit c62c11aecd4e3f8822e1b835fea403acc3148c5a.
    - Set immediate flag for the initial patch Setting immediate to true will simplify installation of the     initial patch and possibly also of the further updates. (bsc#907150)
    - The stubs' signatures have changed: each argument used to get mapped to either long or long long, but on     x86_64, the stubs are now receiving a single struct pt_regs only -- it's their responsibility to extract     the arguments as appropriate. In order to not require each and every live patch touching syscalls to     include an insane amount of ifdeffery, provide a set of #defines hiding it: 1.) KLP_SYSCALL_SYM(name)     expands to the syscall stub name for 64 bits as defined by _SYSCALL_DEFINEx(x, _name, ...). 2.) If the     architeture requires 32bit specific stubs for syscalls sharing a common implementation between 32 and     64bits, the KLP_ARCH_HAS_SYSCALL_COMPAT_STUBS macro is defined. 3.) If KLP_ARCH_HAS_SYSCALL_COMPAT_STUBS     is defined, then KLP_SYSCALL_COMPAT_STUB_SYM(name) expands to the syscall stub name for 32 bits as defined     by _SYSCALL_DEFINEx(x, _name, ...). 4.) For syscalls not sharing a common implementation between 32 and 64     bits, i.e. those defined by COMPAT_SYSCALL_DEFINEx(), the macro KLP_COMPAT_SYSCALL_SYM(name) expands to     the stub name defined as defined by COMPAT_SYSCALL_DEFINEx(x, _name, ...). 5.) Finally, for hiding     differences between the signatures, provide the macro KLP_SYSCALL_DECLx(x, sym, ...) which expands to a     declaration of sym, with the x arguments either mapped to long resp. long long each, or collapsed to a     single struct pt_regs argument as appropriate for the architecture. Note that these macros are defined as     appropriate on kernels before and after 4.17, so that live patch code can be shared. (bsc#1149841)
    - bsc#1249208: fix livepatching target module name (bsc#1252946)
    - uname_patch: convert to the syscall stub wrapper macros from klp_syscalls.h In order to make the live     patch to the newuname() syscall work on kernels >= 4.17 again, convert it to the KLP_SYSCALL_*() wrapper     macros provided by klp_syscalls.h. (bsc#1149841)

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1783791447 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: phy: mdio: fix memory leak Syzbot     reported memory leak in MDIO bus interface, the problem was in wrong state logic. MDIOBUS_ALLOCATED     indicates 2 states: 1. Bus is only allocated 2. Bus allocated and __mdiobus_register() fails, but     device_register() was called In case of device_register() has been called we should call put_device() to     correctly free the memory allocated for this device, but mdiobus_free() calls just kfree(dev) in case of     MDIOBUS_ALLOCATED state To avoid this behaviour we need to set bus->state to MDIOBUS_UNREGISTERED _before_     calling device_register(), because put_device() should be called even in case of device_register()     failure. (CVE-2021-47416)

  - 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)

  - In the Linux kernel, the following vulnerability has been resolved: can: isotp: sanitize CAN ID checks in     isotp_bind() Syzbot created an environment that lead to a state machine status that can not be reached     with a compliant CAN ID address configuration. The provided address information consisted of CAN ID     0x6000001 and 0xC28001 which both boil down to 11 bit CAN IDs 0x001 in sending and receiving. Sanitize the     SFF/EFF CAN ID values before performing the address checks. (CVE-2022-49269)

  - In the Linux kernel, the following vulnerability has been resolved: tty: fix deadlock caused by calling     printk() under tty_port->lock pty_write() invokes kmalloc() which may invoke a normal printk() to print     failure message. This can cause a deadlock in the scenario reported by syz-bot below: CPU0 CPU1 CPU2 ----
    ---- ---- lock(console_owner); lock(&port_lock_key); lock(&port->lock); lock(&port_lock_key);
    lock(&port->lock); lock(console_owner); As commit dbdda842fe96 (printk: Add console owner and waiter     logic to load balance console writes) said, such deadlock can be prevented by using printk_deferred() in     kmalloc() (which is invoked in the section guarded by the port->lock). But there are too many printk() on     the kmalloc() path, and kmalloc() can be called from anywhere, so changing printk() to printk_deferred()     is too complicated and inelegant. Therefore, this patch chooses to specify __GFP_NOWARN to kmalloc(), so     that printk() will not be called, and this deadlock problem can be avoided. Syzbot reported the following     lockdep error: ====================================================== WARNING: possible circular locking     dependency detected 5.4.143-00237-g08ccc19a-dirty #10 Not tainted

  - In the Linux kernel, the following vulnerability has been resolved: list: fix a data-race around     ep->rdllist ep_poll() first calls ep_events_available() with no lock held and checks if ep->rdllist is     empty by list_empty_careful(), which reads rdllist->prev. Thus all accesses to it need some protection to     avoid store/load-tearing. Note INIT_LIST_HEAD_RCU() already has the annotation for both prev and next.
    Commit bf3b9f6372c4 (epoll: Add busy poll support to epoll with socket fds.) added the first lockless     ep_events_available(), and commit c5a282e9635e (fs/epoll: reduce the scope of wq lock in epoll_wait())     made some ep_events_available() calls lockless and added single call under a lock, finally commit     e59d3c64cba6 (epoll: eliminate unnecessary lock for zero timeout) made the last ep_events_available()     lockless.

The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1780562693 advisory.

  - An issue was discovered in the Linux kernel before 5.16.12. drivers/net/usb/sr9700.c allows attackers to     obtain sensitive information from heap memory via crafted frame lengths from a device. (CVE-2022-26966)

  - In the Linux kernel, the following vulnerability has been resolved: kprobes: don't call disarm_kprobe()     for disabled kprobes The assumption in __disable_kprobe() is wrong, and it could try to disarm an already     disarmed kprobe and fire the WARN_ONCE() below.

  - In the Linux kernel, the following vulnerability has been resolved: tracing/hist: Fix out-of-bound write     on 'action_data.var_ref_idx' When generate a synthetic event with many params and then create a trace     action for it [1], kernel panic happened [2]. It is because that in trace_action_create() 'data->n_params'     is up to SYNTH_FIELDS_MAX (current value is 64), and array 'data->var_ref_idx' keeps indices into array     'hist_data->var_refs' for each synthetic event param, but the length of 'data->var_ref_idx' is     TRACING_MAP_VARS_MAX (current value is 16), so out-of-bound write happened when 'data->n_params' more than     16. In this case, 'data->match_data.event' is overwritten and eventually cause the panic. To solve the     issue, adjust the length of 'data->var_ref_idx' to be SYNTH_FIELDS_MAX and add sanity checks to avoid out-     of-bound write.

  - In the Linux kernel, the following vulnerability has been resolved: net: can: j1939: enhanced error     handling for tightly received RTS messages in xtp_rx_rts_session_new This patch enhances error handling in     scenarios with RTS (Request to Send) messages arriving closely. It replaces the less informative     WARN_ON_ONCE backtraces with a new error handling method. This provides clearer error messages and allows     for the early termination of problematic sessions. Previously, sessions were only released at the end of     j1939_xtp_rx_rts(). Potentially this could be reproduced with something like: testj1939 -r vcan0:0x80 &     while true; do # send first RTS cansend vcan0 18EC8090#1014000303002301; # send second RTS cansend vcan0     18EC8090#1014000303002301; # send abort cansend vcan0 18EC8090#ff00000000002301; done (CVE-2023-52887)

  - In the Linux kernel, the following vulnerability has been resolved: net: fec: remove .ndo_poll_controller     to avoid deadlocks There is a deadlock issue found in sungem driver, please refer to the commit     ac0a230f719b (eth: sungem: remove .ndo_poll_controller to avoid deadlocks). The root cause of the issue     is that netpoll is in atomic context and disable_irq() is called by .ndo_poll_controller interface of     sungem driver, however, disable_irq() might sleep. After analyzing the implementation of     fec_poll_controller(), the fec driver should have the same issue. Due to the fec driver uses NAPI for TX     completions, the .ndo_poll_controller is unnecessary to be implemented in the fec driver, so     fec_poll_controller() can be safely removed. (CVE-2024-38553)
