    scsi: target: tcm_loop: Fix segfault in tcm_loop_tpg_address_show()

    In the Linux kernel, the following vulnerability has been resolved: scsi: target: tcm_loop: Fix segfault in tcm_loop_tpg_address_show() If the allocation of tl_hba->sh fails in tcm_loop_driver_probe() and we attempt to dereference it in tcm_loop_tpg_address_show() we will get a segfault, see below for an example. So, check tl_hba->sh before dereferencing it.

    drm/radeon: delete radeon_fence_process in is_signaled, no deadlock

    In the Linux kernel, the following vulnerability has been resolved: drm/radeon: delete radeon_fence_process in is_signaled, no deadlock Delete the attempt to progress the queue when checking if fence is signaled. This avoids deadlock. dma-fence_ops::signaled can be called with the fence lock in unknown state. For radeon, the fence lock is also the wait queue lock. This can cause a self deadlock when signaled() tries to make forward progress on the wait queue. But advancing the queue is unneeded because incorrectly returning false from signaled() is perfectly acceptable. (cherry picked from commit 527ba26e50ec2ca2be9c7c82f3ad42998a75d0db)

    net: ethernet: ti: netcp: Standardize knav_dma_open_channel to return NULL on error

    In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ti: netcp: Standardize knav_dma_open_channel to return NULL on error Make knav_dma_open_channel consistently return NULL on error instead of ERR_PTR. Currently the header include/linux/soc/ti/knav_dma.h returns NULL when the driver is disabled, but the driver implementation does not even return NULL or ERR_PTR on failure, causing inconsistency in the users. This results in a crash in netcp_free_navigator_resources as followed (trimmed): Unhandled fault: alignment exception (0x221) at 0xfffffff2 [fffffff2] *pgd=80000800207003, *pmd=82ffda003, *pte=00000000 In

    Input: pegasus-notetaker - fix potential out-of-bounds access

    In the Linux kernel, the following vulnerability has been resolved: Input: pegasus-notetaker - fix potential out-of-bounds access In the pegasus_notetaker driver, the pegasus_probe() function allocates the URB transfer buffer using the wMaxPacketSize value from the endpoint descriptor. An attacker can use a malicious USB descriptor to force the allocation of a very small buffer. Subsequently, if the device sends an interrupt packet with a specific pattern (e.g., where the first byte is 0x80 or 0x42), the pegasus_parse_packet() function parses the packet without checking the allocated buffer size. This leads to an out-of-bounds memory acces

    timers: Fix NULL function pointer race in timer_shutdown_sync()

    In the Linux kernel, the following vulnerability has been resolved: timers: Fix NULL function pointer race in timer_shutdown_sync() There is a race condition between timer_shutdown_sync() and timer expiration that can lead to hitting a WARN_ON in expire_timers(). The issue occurs when timer_shutdown_sync() clears the timer function to NULL while the timer is still running on another CPU. The race scenario looks like this: CPU0 CPU1 <SOFTIRQ> lock_timer_base() expire_timers() base->running_timer = timer; unlock_timer_base() [call_timer_fn enter] mod_timer() ... timer_shutdown_sync() lock_timer_ba

    ksm: use range-walk function to jump over holes in scan_get_next_rmap_item

    In the Linux kernel, the following vulnerability has been resolved: ksm: use range-walk function to jump over holes in scan_get_next_rmap_item Currently, scan_get_next_rmap_item() walks every page address in a VMA to locate mergeable pages. This becomes highly inefficient when scanning large virtual memory areas that contain mostly unmapped regions, causing ksmd to use large amount of cpu without deduplicating much pages. This patch replaces the per-address lookup with a range walk using walk_page_range(). The range walker allows KSM to skip over entire unmapped holes in a VMA, avoiding unnecessary lookups. This problem was previously d

    netfilter: nft_ct: add seqadj extension for natted connections

    In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_ct: add seqadj extension for natted connections Sequence adjustment may be required for FTP traffic with PASV/EPSV modes. due to need to re-write packet payload (IP, port) on the ftp control connection. This can require changes to the TCP length and expected seq / ack_seq. The easiest way to reproduce this issue is with PASV mode. Example ruleset: table inet ftp_nat { ct helper ftp_helper { type "ftp" protocol tcp l3proto inet } chain prerouting { type filter hook prerouting priority 0;

    In the Linux kernel, the following vulnerability has been resolved: pmdomain: arm: scmi: Fix genpd leak on provider registration failure If of_genpd_add_provider_onecell() fails during probe, the previously created generic power domains are not removed, leading to a memory leak and potential kernel crash later in genpd_debug_add(). Add proper error handling to unwind the initialized domains before returning from probe to ensure all resources are correctly released on failure.

    media: imon: make send_packet() more robust

    In the Linux kernel, the following vulnerability has been resolved: media: imon: make send_packet() more robust syzbot is reporting that imon has three problems which result in hung tasks due to forever holding device lock [1]. First problem is that when usb_rx_callback_intf0() once got -EPROTO error after ictx->dev_present_intf0 became true, usb_rx_callback_intf0() resubmits urb after printk(), and resubmitted urb causes usb_rx_callback_intf0() to again get -EPROTO error. This results in printk() flooding (RCU stalls). Alan Stern commented [2] that In theory it's okay to resubmit _if_ the driver has a robust error-recovery scheme (s

    net: usb: qmi_wwan: initialize MAC header offset in qmimux_rx_fixup

    In the Linux kernel, the following vulnerability has been resolved: net: usb: qmi_wwan: initialize MAC header offset in qmimux_rx_fixup Raw IP packets have no MAC header, leaving skb->mac_header uninitialized. This can trigger kernel panics on ARM64 when xfrm or other subsystems access the offset due to strict alignment checks. Initialize the MAC header to prevent such crashes. This can trigger kernel panics on ARM when running IPsec over the qmimux0 interface.

    In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/atom: Check kcalloc() for WS buffer in amdgpu_atom_execute_table_locked() kcalloc() may fail. When WS is non-zero and allocation fails, ectx.ws remains NULL while ectx.ws_size is set, leading to a potential NULL pointer dereference in atom_get_src_int() when accessing WS entries. Return -ENOMEM on allocation failure to avoid the NULL dereference.

    nfs4_setup_readdir(): insufficient locking for ->d_parent->d_inode dereferencing

    In the Linux kernel, the following vulnerability has been resolved: nfs4_setup_readdir(): insufficient locking for ->d_parent->d_inode dereferencing Theoretically it's an oopsable race, but I don't believe one can manage to hit it on real hardware; might become doable on a KVM, but it still won't be easy to attack. Anyway, it's easy to deal with - since xdr_encode_hyper() is just a call of put_unaligned_be64(), we can put that under ->d_lock and be done with that.

    ftrace: Fix softlockup in ftrace_module_enable

    In the Linux kernel, the following vulnerability has been resolved: ftrace: Fix softlockup in ftrace_module_enable A soft lockup was observed when loading amdgpu module. If a module has a lot of tracable functions, multiple calls to kallsyms_lookup can spend too much time in RCU critical section and with disabled preemption, causing kernel panic. This is the same issue that was fixed in commit d0b24b4e91fc ("ftrace: Prevent RCU stall on PREEMPT_VOLUNTARY kernels") and commit 42ea22e754ba ("ftrace: Add cond_resched() to ftrace_graph_set_hash()"). Fix it the same way by adding cond_resched() in ftrace_module_enable.

    jfs: fix uninitialized waitqueue in transaction manager

    In the Linux kernel, the following vulnerability has been resolved: jfs: fix uninitialized waitqueue in transaction manager The transaction manager initialization in txInit() was not properly initializing TxBlock[0].waitor waitqueue, causing a crash when txEnd(0) is called on read-only filesystems. When a filesystem is mounted read-only, txBegin() returns tid=0 to indicate no transaction. However, txEnd(0) still gets called and tries to access TxBlock[0].waitor via tid_to_tblock(0), but this waitqueue was never initialized because the initialization loop started at index 1 instead of 0. This causes a 'non-static key' lockdep warning and s
