In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Clear cmds after chip reset Commit aefed3e5548f ("scsi: qla2xxx: target: Fix offline port handling and host reset handling") caused two problems: 1. Commands sent to FW, after chip reset got stuck and never freed as FW is not going to respond to them anymore. 2. BUG_ON(cmd->sg_mapped) in qlt_free_cmd(). Commit 26f9ce53817a ("scsi: qla2xxx: Fix missed DMA unmap for aborted commands") attempted to fix this, but introduced another bug under different circumstances when two different CPUs were racing to call qlt_unmap_sg() at the same time: BUG_ON(!valid_dma_direction(dir)) in dma_unmap_sg_attrs(). So revert "scsi: qla2xxx: Fix missed DMA unmap for aborted commands" and partially revert "scsi: qla2xxx: target: Fix offline port handling and host reset handling" at __qla2x00_abort_all_cmds.

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix improper freeing of purex item In qla2xxx_process_purls_iocb(), an item is allocated via qla27xx_copy_multiple_pkt(), which internally calls qla24xx_alloc_purex_item(). The qla24xx_alloc_purex_item() function may return a pre-allocated item from a per-adapter pool for small allocations, instead of dynamically allocating memory with kzalloc(). An error handling path in qla2xxx_process_purls_iocb() incorrectly uses kfree() to release the item. If the item was from the pre-allocated pool, calling kfree() on it is a bug that can lead to memory corruption. Fix this by using the correct deallocation function, qla24xx_free_purex_item(), which properly handles both dynamically allocated and pre-allocated items.

In the Linux kernel, the following vulnerability has been resolved: ixgbe: Fix panic during XDP_TX with > 64 CPUs Commit 4fe815850bdc ("ixgbe: let the xdpdrv work with more than 64 cpus") adds support to allow XDP programs to run on systems with more than 64 CPUs by locking the XDP TX rings and indexing them using cpu % 64 (IXGBE_MAX_XDP_QS). Upon trying this out patch on a system with more than 64 cores, the kernel paniced with an array-index-out-of-bounds at the return in ixgbe_determine_xdp_ring in ixgbe.h, which means ixgbe_determine_xdp_q_idx was just returning the cpu instead of cpu % IXGBE_MAX_XDP_QS.

However, immediately after this, the rings are reconfigured by ixgbe_setup_tc. ixgbe_setup_tc calls ixgbe_clear_interrupt_scheme which calls ixgbe_free_q_vectors which calls ixgbe_free_q_vector in a loop. ixgbe_free_q_vector decrements ixgbe_xdp_locking_key once per call if it is non-zero. Commenting out the decrement in ixgbe_free_q_vector stopped my system from panicing. I suspect to make the original patch work, I would need to load an XDP program and then replace it in order to get ixgbe_xdp_locking_key back above 0 since ixgbe_setup_tc is only called when transitioning between XDP and non-XDP ring configurations, while ixgbe_xdp_locking_key is incremented every time ixgbe_xdp_setup is called. Also, ixgbe_setup_tc can be called via ethtool --set-channels, so this becomes another path to decrement ixgbe_xdp_locking_key to 0 on systems with more than 64 CPUs. Since ixgbe_xdp_locking_key only protects the XDP_TX path and is tied to the number of CPUs present, there is no reason to disable it upon unloading an XDP program. To avoid confusion, I have moved enabling ixgbe_xdp_locking_key into ixgbe_sw_init, which is part of the probe path.

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix missed ses refcounting Use new cifs_smb_ses_inc_refcount() helper to get an active reference of @ses and @ses->dfs_root_ses (if set). This will prevent @ses->dfs_root_ses of being put in the next call to cifs_put_smb_ses() and thus potentially causing an use-after-free bug.

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: add bounds check on Transfer Tag ttag is used as an index to get cmd in nvmet_tcp_handle_h2c_data_pdu(), add a bounds check to avoid out-of-bounds access.

In the Linux kernel, the following vulnerability has been resolved: crypto: aead - Fix reqsize handling Commit afddce13ce81d ("crypto: api - Add reqsize to crypto_alg") introduced cra_reqsize field in crypto_alg struct to replace type specific reqsize fields. It looks like this was introduced specifically for ahash and acomp from the commit description as subsequent commits add necessary changes in these alg frameworks. However, this is being recommended for use in all crypto algs instead of setting reqsize using crypto_*_set_reqsize(). Using cra_reqsize in aead algorithms, hence, causes memory corruptions and crashes as the underlying functions in the algorithm framework have not been updated to set the reqsize properly from cra_reqsize. [1] Add proper set_reqsize calls in the aead init function to properly initialize reqsize for these algorithms in the framework.

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix double free of qgroup record after failure to add delayed ref head In the previous code it was possible to incur into a double kfree() scenario when calling add_delayed_ref_head(). This could happen if the record was reported to already exist in the btrfs_qgroup_trace_extent_nolock() call, but then there was an error later on add_delayed_ref_head(). In this case, since add_delayed_ref_head() returned an error, the caller went to free the record. Since add_delayed_ref_head() couldn't set this kfree'd pointer to NULL, then kfree() would have acted on a non-NULL 'record' object which was pointing to memory already freed by the callee. The problem comes from the fact that the responsibility to kfree the object is on both the caller and the callee at the same time. Hence, the fix for this is to shift the ownership of the 'qrecord' object out of the add_delayed_ref_head(). That is, we will never attempt to kfree() the given object inside of this function, and will expect the caller to act on the 'qrecord' object on its own. The only exception where the 'qrecord' object cannot be kfree'd is if it was inserted into the tracing logic, for which we already have the 'qrecord_inserted_ret' boolean to account for this. Hence, the caller has to kfree the object only if add_delayed_ref_head() reports not to have inserted it on the tracing logic. As a side-effect of the above, we must guarantee that 'qrecord_inserted_ret' is properly initialized at the start of the function, not at the end, and then set when an actual insert happens. This way we avoid 'qrecord_inserted_ret' having an invalid value on an early exit. The documentation from the add_delayed_ref_head() has also been updated to reflect on the exact ownership of the 'qrecord' object.

In the Linux kernel, the following vulnerability has been resolved: x86/sev: Make enc_dec_hypercall() accept a size instead of npages enc_dec_hypercall() accepted a page count instead of a size, which forced its callers to round up. As a result, non-page aligned vaddrs caused pages to be spuriously marked as decrypted via the encryption status hypercall, which in turn caused consistent corruption of pages during live migration. Live migration requires accurate encryption status information to avoid migrating pages from the wrong perspective.

In the Linux kernel, the following vulnerability has been resolved: ceph: fix potential use-after-free bug when trimming caps When trimming the caps and just after the 'session->s_cap_lock' is released in ceph_iterate_session_caps() the cap maybe removed by another thread, and when using the stale cap memory in the callbacks it will trigger use-after-free crash. We need to check the existence of the cap just after the 'ci->i_ceph_lock' being acquired. And do nothing if it's already removed.

The Print Invoice & Delivery Notes for WooCommerce plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 5.8.0 via the 'WooCommerce_Delivery_Notes::update' function. This is due to missing capability check in the 'WooCommerce_Delivery_Notes::update' function, PHP enabled in Dompdf, and missing escape in the 'template.php' file. This makes it possible for unauthenticated attackers to execute code on the server.

5ire is a cross-platform desktop artificial intelligence assistant and model context protocol client. In versions 0.15.2 and prior, an RCE vulnerability exists in useMarkdown.ts, where the markdown-it-mermaid plugin is initialized with securityLevel: 'loose'. This configuration explicitly permits the rendering of HTML tags within Mermaid diagram nodes. This issue has not been patched at time of publication.

LangChain is a framework for building agents and LLM-powered applications. Prior to versions 0.3.81 and 1.2.5, a serialization injection vulnerability exists in LangChain's dumps() and dumpd() functions. The functions do not escape dictionaries with 'lc' keys when serializing free-form dictionaries. The 'lc' key is used internally by LangChain to mark serialized objects. When user-controlled data contains this key structure, it is treated as a legitimate LangChain object during deserialization rather than plain user data. This issue has been patched in versions 0.3.81 and 1.2.5.

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to version 4.0.0-beta.451, an authenticated command injection vulnerability in the Database Backup functionality allows users with application/service management permissions to execute arbitrary commands as root on managed servers. Database names used in backup operations are passed directly to shell commands without sanitization, enabling full remote code execution. Version 4.0.0-beta.451 fixes the issue.
