nfsd: Fix cred ref leak in nfsd_nl_threads_set_doit().
In the Linux kernel, the following vulnerability has been resolved: nfsd: Fix cred ref leak in nfsd_nl_threads_set_doit(). syzbot reported memory leak of struct cred. [0] nfsd_nl_threads_set_doit() passes get_current_cred() to nfsd_svc(), but put_cred() is not called after that. The cred is finally passed down to _svc_xprt_create(), which calls get_cred() with the cred for struct svc_xprt. The ownership of the refcount by get_current_cred() is not transferred to anywhere and is just leaked. nfsd_svc() is also called from write_threads(), but it does not bump file->f_cred there. nfsd_nl_threads_set_doit() is called from sendmsg() and current->cred does not go away. Let's use current_cred() in nfsd_nl_threads_set_doit().

UltraJSON has a Memory Leak parsing large integers allows DoS
UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. Versions 5.4.0 through 5.11.0 contain an accumulating memory leak in JSON parsing large (outside of the range [-2^63, 2^64 - 1]) integers. The leaked memory is a copy of the string form of the integer plus an additional NULL byte. The leak occurs irrespective of whether the integer parses successfully or is rejected due to having more than sys.get_int_max_str_digits() digits, meaning that any sized leak per malicious JSON can be achieved provided that there is no limit on the overall size of the payload. Any service that calls ujson.load()/ujson.loads()/ujson.decode() on untrusted inputs is affected and vulnerable to denial of service attacks. This issue has been fixed in version 5.12.0.

OpenWrt Project jsonpath: Memory leak when processing strings, labels, and regexp tokens
OpenWrt Project is a Linux operating system targeting embedded devices. In versions prior to both 24.10.6 and 25.12.1, the jp_get_token function, which performs lexical analysis by breaking input expressions into tokens, contains a memory leak vulnerability when extracting string literals, field labels, and regular expressions using dynamic memory allocation. These extracted results are stored in a jp_opcode struct, which is later copied to a newly allocated jp_opcode object via jp_alloc_op. During this transfer, if a string was previously extracted and stored in the initial jp_opcode, it is copied to the new allocation but the original memory is never freed, resulting in a memory leak. This issue has been fixed in versions 24.10.6 and 25.12.1.

CVE-2026-23261 Média · 5.5 CWE-401 18/03/2026
nvme-fc: release admin tagset if init fails
In the Linux kernel, the following vulnerability has been resolved: nvme-fc: release admin tagset if init fails nvme_fabrics creates an NVMe/FC controller in following path: nvmf_dev_write() -> nvmf_create_ctrl() -> nvme_fc_create_ctrl() -> nvme_fc_init_ctrl() nvme_fc_init_ctrl() allocates the admin blk-mq resources right after nvme_add_ctrl() succeeds. If any of the subsequent steps fail (changing the controller state, scheduling connect work, etc.), we jump to the fail_ctrl path, which tears down the controller references but never frees the admin queue/tag set. The leaked blk-mq allocations match the kmemleak report seen during blktests nvme/fc. Check ctrl->ctrl.admin_tagset in the fail_ctrl path and call nvme_remove_admin_tag_set() when it is set so that all admin queue allocations are reclaimed whenever controller setup aborts.

regmap: maple: free entry on mas_store_gfp() failure
In the Linux kernel, the following vulnerability has been resolved: regmap: maple: free entry on mas_store_gfp() failure regcache_maple_write() allocates a new block ('entry') to merge adjacent ranges and then stores it with mas_store_gfp(). When mas_store_gfp() fails, the new 'entry' remains allocated and is never freed, leaking memory. Free 'entry' on the failure path; on success continue freeing the replaced neighbor blocks ('lower', 'upper').
CVE-2026-23258 Média · 5.5 CWE-401 18/03/2026
net: liquidio: Initialize netdev pointer before queue setup
In the Linux kernel, the following vulnerability has been resolved: net: liquidio: Initialize netdev pointer before queue setup In setup_nic_devices(), the netdev is allocated using alloc_etherdev_mq(). However, the pointer to this structure is stored in oct->props[i].netdev only after the calls to netif_set_real_num_rx_queues() and netif_set_real_num_tx_queues(). If either of these functions fails, setup_nic_devices() returns an error without freeing the allocated netdev. Since oct->props[i].netdev is still NULL at this point, the cleanup function liquidio_destroy_nic_device() will fail to find and free the netdev, resulting in a memory leak. Fix this by initializing oct->props[i].netdev before calling the queue setup functions. This ensures that the netdev is properly accessible for cleanup in case of errors. Compile tested only. Issue found using a prototype static analysis tool and code review.
CVE-2025-71268 Média · 5.5 CWE-401 18/03/2026
btrfs: fix reservation leak in some error paths when inserting inline extent
In the Linux kernel, the following vulnerability has been resolved: btrfs: fix reservation leak in some error paths when inserting inline extent If we fail to allocate a path or join a transaction, we return from __cow_file_range_inline() without freeing the reserved qgroup data, resulting in a leak. Fix this by ensuring we call btrfs_qgroup_free_data() in such cases.

CVE-2024-14027 Média · 5.5 CWE-401 09/03/2026
xattr: switch to CLASS(fd)
In the Linux kernel, the following vulnerability has been resolved: fs/xattr: missing fdput() in fremovexattr error path In the Linux kernel, the fremovexattr() syscall calls fdget() to acquire a file reference but returns early without calling fdput() when strncpy_from_user() fails on the name argument. In multi-threaded processes where fdget() takes the slow path, this permanently leaks one file reference per call, pinning the struct file and associated kernel objects in memory. An unprivileged local user can exploit this to cause kernel memory exhaustion. The issue was inadvertently fixed by commit a71874379ec8 ("xattr: switch to CLASS(fd)").
