2024-12-29 CVE-2024-56755 Memory Leak vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: netfs/fscache: Add a memory barrier for FSCACHE_VOLUME_CREATING In fscache_create_volume(), there is a missing memory barrier between the bit-clearing operation and the wake-up operation.

2024-12-29 CVE-2024-56756 Unspecified vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix freeing of the HMB descriptor table The HMB descriptor table is sized to the maximum number of descriptors that could be used for a given device, but __nvme_alloc_host_mem could break out of the loop earlier on memory allocation failure and end up using less descriptors than planned for, which leads to an incorrect size passed to dma_free_coherent. In practice this was not showing up because the number of descriptors tends to be low and the dma coherent allocator always allocates and frees at least a page.

2024-12-29 CVE-2024-56710 Memory Leak vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: ceph: fix memory leak in ceph_direct_read_write() The bvecs array which is allocated in iter_get_bvecs_alloc() is leaked and pages remain pinned if ceph_alloc_sparse_ext_map() fails. There is no need to delay the allocation of sparse_ext map until after the bvecs array is set up, so fix this by moving sparse_ext allocation a bit earlier.

2024-12-29 CVE-2024-56711 NULL Pointer Dereference vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: drm/panel: himax-hx83102: Add a check to prevent NULL pointer dereference drm_mode_duplicate() could return NULL due to lack of memory, which will then call NULL pointer dereference.

2024-12-29 CVE-2024-56712 Memory Leak vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: udmabuf: fix memory leak on last export_udmabuf() error path In export_udmabuf(), if dma_buf_fd() fails because the FD table is full, a dma_buf owning the udmabuf has already been created; but the error handling in udmabuf_create() will tear down the udmabuf without doing anything about the containing dma_buf. This leaves a dma_buf in memory that contains a dangling pointer; though that doesn't seem to lead to anything bad except a memory leak. Fix it by moving the dma_buf_fd() call out of export_udmabuf() so that we can give it different error handling. Note that the shape of this code changed a lot in commit 5e72b2b41a21 ("udmabuf: convert udmabuf driver to use folios"); but the memory leak seems to have existed since the introduction of udmabuf.

2024-12-29 CVE-2024-56715 Memory Leak vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: ionic: Fix netdev notifier unregister on failure If register_netdev() fails, then the driver leaks the netdev notifier. Fix this by calling ionic_lif_unregister() on register_netdev() failure.

In the Linux kernel, the following vulnerability has been resolved: net: mscc: ocelot: fix incorrect IFH SRC_PORT field in ocelot_ifh_set_basic() Packets injected by the CPU should have a SRC_PORT field equal to the CPU port module index in the Analyzer block (ocelot->num_phys_ports). The blamed commit copied the ocelot_ifh_set_basic() call incorrectly from ocelot_xmit_common() in net/dsa/tag_ocelot.c.

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: fix TSO DMA API usage causing oops Commit 66600fac7a98 ("net: stmmac: TSO: Fix unbalanced DMA map/unmap for non-paged SKB data") moved the assignment of tx_skbuff_dma[]'s members to be later in stmmac_tso_xmit(). The buf (dma cookie) and len stored in this structure are passed to dma_unmap_single() by stmmac_tx_clean().
