    f2fs: accurately adjust free_sections during free_segment_range

    In the Linux kernel, the following vulnerability has been resolved: f2fs: accurately adjust free_sections during free_segment_range In free_segment_range(), MAIN_SECS(sbi) is temporarily reduced by `secs` to restrict block allocation to the safe remaining main area while valid blocks in the truncated range are evacuated by GC. However, FREE_I(sbi)->free_sections tracks the total number of free sections across the whole filesystem. If any sections within the truncated range were already free upon entering free_segment_range(), failing to deduct them from free_sections causes the filesystem to overestimate available free sections in the acti

    scsi: qla2xxx: Null out freed pointers in qla2x00_mem_alloc() error path

    In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Null out freed pointers in qla2x00_mem_alloc() error path When qla2x00_mem_alloc() fails, qla2x00_probe_one() jumps to probe_hw_failed and calls qla2x00_mem_free(). Several error labels in qla2x00_mem_alloc() freed adapter members (elsrej.c, purex_dma_pool, flt, sfp_data, loop_id_map, async_pd, sf_init_cb, ex_init_cb, npiv_info) but left the pointers dangling. qla2x00_mem_free() then freed them a second time. Worse, for the dma_pool members it issued dma_pool_free(ha->s_dma_pool, ...) after s_dma_pool had already been destroyed and set to NULL at fail_s_dma_p

    scsi: qla2xxx: Skip vport under deletion in report ID acquisition

    In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Skip vport under deletion in report ID acquisition qla24xx_report_id_acquisition() format-1 handling walks ha->vp_list under vport_slock, takes a vref_count on the matching vport and calls qla_update_host_map() to register its port id. A vport teardown via qla24xx_vport_delete() sets VPORT_DELETE, then qla24xx_disable_vp() removes the vport from the host_map btree and zeroes vha->d_id (RESET_AL_PA). The vport is only unlinked from vp_list later, in qla24xx_deallocate_vp_id(), which clears vp_map[idx] (RESET_VP_IDX) but does not touch host_map. In the window

    scsi: qla2xxx: Fix soft lockup polling continuation IOCB signature

    In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix soft lockup polling continuation IOCB signature qla27xx_copy_multiple_pkt() and qla27xx_copy_fpin_pkt() poll rsp_q->ring_ptr->signature for RESPONSE_PROCESSED (0xDEADDEAD) to decide whether the next continuation IOCB has arrived, spinning on cpu_relax() without advancing the ring or decrementing the entry count while it has not. response_t::signature lives at byte offset 60, but a continuation IOCB (sts_cont_entry_t / struct sts_cont_entry_ext) carries raw FC frame payload at that offset (data[56..59]).

    scsi: qla2xxx: Validate BSG request_len before reading vendor_cmd[]

    In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Validate BSG request_len before reading vendor_cmd[] The FC BSG transport allocates job->request via memdup_user() using the exact user-supplied request_len. For FC_BSG_HST_VENDOR, fc_bsg_host_dispatch() only guarantees request_len covers msgcode and vendor_id; it does not account for the vendor_cmd[] flexible array. qla2xxx then reads the command selector vendor_cmd[0] and, in several sub-handlers, vendor_cmd[1]/[2] or structures overlaid on the vendor command area without verifying request_len. A caller holding CAP_SYS_RAWIO can submit a short request whos

    mptcp: avoid unneeded actions on subflow reset

    In the Linux kernel, the following vulnerability has been resolved: mptcp: avoid unneeded actions on subflow reset Once in a blue moon, the mptcp receive path can recursively call mptcp_data_ready() via state change under unlucky error conditions, and then try to hold the data lock again. Break the recursion loop explicitly checking for the exceptional condition. Add a new flag instead of using an existing one like 'closing', to exit early in subflow_state_change(), and explicitly flush the RX queue at reset time. This avoids unneeded processing to check for available data -- calling get_mapping_status() and more on a dying subflow -- bu

    gfs2: fix quota init duplicate scan

    In the Linux kernel, the following vulnerability has been resolved: gfs2: fix quota init duplicate scan gfs2_quota_init() checks for duplicate quota_change IDs while holding qd_lock and the quota hash bucket bitlock. That path used gfs2_qd_search_bucket(), which takes a lockref reference via lockref_get_not_dead(). On PREEMPT_RT this may sleep, which is not allowed under the bucket bitlock, triggering "sleeping function called from invalid context". Use a no-ref bucket lookup in this path, then continue duplicate handling without taking a lockref there. Refactor gfs2_qd_search_bucket() to build on top of the no-ref helper so lookup trave

    drm/xe: Fix null pointer dereference in devcoredump cleanup

Guard the xe_guc_capture_put_matched_nodes() call with IS_ERR_OR_NULL() to prevent a null dereference. In xe_devcoredump_free(), the deferred work is only queued when a coredump is captured, so guard cancel_work_sync() with a check on coredump->captured.

    wifi: cfg80211: reject duplicate wiphy cipher suite entries

    In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: reject duplicate wiphy cipher suite entries Duplicate entries in wiphy->cipher_suites do not describe any additional capability, but cfg80211 currently accepts them and leaves individual consumers to deal with them. One such consumer is the WEXT compatibility code, which appends a WEP key length for each WEP cipher entry it sees. Repeated WEP entries can therefore overflow the fixed iw_range::encoding_size array returned by SIOCGIWRANGE. Reject duplicate cipher suite entries in wiphy_register() instead. This keeps the cipher suite invariant in one place an

    wifi: rtw88: Add NULL check for chip->edcca_th in rtw_fw_adaptivity_result()

    In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: Add NULL check for chip->edcca_th in rtw_fw_adaptivity_result() It was recently reported that rtw_fw_adaptivity_result() in fw.c dereferences rtwdev->chip->edcca_th without a NULL check. The issue is that devices with the 8821CE chip don't define edcca_th in their chip info. As a result, when rtw_fw_adaptivity_result() tries to dereference it, the kernel triggers an oops. Add a NULL check for edcca_th before dereferencing it in rtw_fw_adaptivity_result() in fw.c. Placing the check at the function entry avoids logging any garbage values. This change does not a

    i3c: master: svc: Prevent IRQ storm from false SLVSTART on NPCM845

    In the Linux kernel, the following vulnerability has been resolved: i3c: master: svc: Prevent IRQ storm from false SLVSTART on NPCM845 On NPCM845, when a target on the I3C bus gets stuck holding SDA low, the controller reports a false Master Request (MR) in-band interrupt event. The driver handles this by emitting a STOP condition to restore the bus. However, the hardware quirk SVC_I3C_QUIRK_FALSE_SLVSTART indicates that emitting a STOP condition may spuriously set the SLVSTART interrupt status bit. In the Master Request case, this creates a feedback loop: the STOP triggers a new SLVSTART event, the IRQ handler fires again, the controller

    media: chips-media: wave5: Fix Reports from Kernel Lock Validator

    In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Fix Reports from Kernel Lock Validator handle_dynamic_resolution change requires that the state_lock be acquired based on the lockdep_assert_held. However, the handle_dynamic_resolution_change call in initialize_sequence does not properly obtain the lock before calling. Since the v4l2_ctrl_find and s_ctrl can sleep, they should not be called while a lock is already held. Store off the fbc_buf_count then properly update control once lock has been freed.

    In the Linux kernel, the following vulnerability has been resolved: spi: spi-qcom-qspi: Fix incomplete error handling in runtime PM The runtime PM functions had incomplete error handling that could leave the system in an inconsistent state. If any operation failed midway through suspend or resume, some resources would be left in the wrong state while others were already changed, leading to potential clock/power imbalances.

    In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: avoid out-of-bounds access in monitor In NAN, we don't know on what band the frame will be sent. Therefore we set info->band to NUM_NL80211_BANDS. However, this leads to out-of-bound access in ieee80211_add_tx_radiotap_header when we try to access the sbands array. Fix it by not accessing the array if the band is NUM_NL80211_BANDS. This means that we will not report rate info for legacy rate in NAN. But nobody really cares about it.
