https://notcve.org/view.php?id=CVE-2024-44971
In the Linux kernel, the following vulnerability has been resolved: net: dsa: bcm_sf2: Fix a possible memory leak in bcm_sf2_mdio_register() bcm_sf2_mdio_register() calls of_phy_find_device() and then phy_device_remove() in a loop to remove existing PHY devices. of_phy_find_device() eventually calls bus_find_device(), which calls get_device() on the returned struct device * to increment the refcount. The current implementation does not decrement the refcount, which causes memory leak. This commit adds the missing phy_device_free() call to decrement the refcount via put_device() to balance the refcount. • https://git.kernel.org/stable/c/771089c2a485958e423f305e974303760167b45c https://git.kernel.org/stable/c/b7b8d9f5e679af60c94251fd6728dde34be69a71 https://git.kernel.org/stable/c/c05516c072903f6fb9134b8e7e1ad4bffcdc4819 https://git.kernel.org/stable/c/7feef10768ea71d468d9bbc1e0d14c461876768c https://git.kernel.org/stable/c/a7d2808d67570e6acae45c2a96e0d59986888e4c https://git.kernel.org/stable/c/f3d5efe18a11f94150fee8b3fda9d62079af640a https://git.kernel.org/stable/c/e3862093ee93fcfbdadcb7957f5f8974fffa806a •

https://notcve.org/view.php?id=CVE-2024-44970
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: SHAMPO, Fix invalid WQ linked list unlink When all the strides in a WQE have been consumed, the WQE is unlinked from the WQ linked list (mlx5_wq_ll_pop()). For SHAMPO, it is possible to receive CQEs with 0 consumed strides for the same WQE even after the WQE is fully consumed and unlinked. This triggers an additional unlink for the same wqe which corrupts the linked list. Fix this scenario by accepting 0 sized consumed strides without unlinking the WQE again. • https://git.kernel.org/stable/c/7b379353e9144e1f7460ff15f39862012c9d0d78 https://git.kernel.org/stable/c/650e24748e1e0a7ff91d5c72b72a2f2a452b5b76 https://git.kernel.org/stable/c/50d8009a0ac02c3311b23a0066511f8337bd88d9 https://git.kernel.org/stable/c/fba8334721e266f92079632598e46e5f89082f30 •

https://notcve.org/view.php?id=CVE-2024-44969
In the Linux kernel, the following vulnerability has been resolved: s390/sclp: Prevent release of buffer in I/O When a task waiting for completion of a Store Data operation is interrupted, an attempt is made to halt this operation. If this attempt fails due to a hardware or firmware problem, there is a chance that the SCLP facility might store data into buffers referenced by the original operation at a later time. Handle this situation by not releasing the referenced data buffers if the halt attempt fails. For current use cases, this might result in a leak of few pages of memory in case of a rare hardware/firmware malfunction. • https://git.kernel.org/stable/c/7a7e60ed23d471a07dbbe72565d2992ee8244bbe https://git.kernel.org/stable/c/1ec5ea9e25f582fd6999393e2f2c3bf56f234e05 https://git.kernel.org/stable/c/a3e52a4c22c846858a6875e1c280030a3849e148 https://git.kernel.org/stable/c/a88a49473c94ccfd8dce1e766aacf3c627278463 https://git.kernel.org/stable/c/46f67233b011385d53cf14d272431755de3a7c79 https://git.kernel.org/stable/c/1e8b7fb427af6b2ddd54eff66a6b428a81c96633 https://git.kernel.org/stable/c/2429ea3b4330e3653b72b210a0d5f2a717359506 https://git.kernel.org/stable/c/bf365071ea92b9579d5a272679b74052a •

https://notcve.org/view.php?id=CVE-2024-44966
In the Linux kernel, the following vulnerability has been resolved: binfmt_flat: Fix corruption when not offsetting data start Commit 04d82a6d0881 ("binfmt_flat: allow not offsetting data start") introduced a RISC-V specific variant of the FLAT format which does not allocate any space for the (obsolete) array of shared library pointers. However, it did not disable the code which initializes the array, resulting in the corruption of sizeof(long) bytes before the DATA segment, generally the end of the TEXT segment. Introduce MAX_SHARED_LIBS_UPDATE which depends on the state of CONFIG_BINFMT_FLAT_NO_DATA_START_OFFSET to guard the initialization of the shared library pointer region so that it will only be initialized if space is reserved for it. • https://git.kernel.org/stable/c/04d82a6d0881ef1ab1e9f66f10805177ee2fb1e8 https://git.kernel.org/stable/c/3a684499261d0f7ed5ee72793025c88c2276809c https://git.kernel.org/stable/c/af65d5383854cc3f172a7d0843b628758bf462c8 https://git.kernel.org/stable/c/49df34d2b7da9e57c839555a2f7877291ce45ad1 https://git.kernel.org/stable/c/9350ba06ee61db392c486716ac68ecc20e030f7c https://git.kernel.org/stable/c/3eb3cd5992f7a0c37edc8d05b4c38c98758d8671 •

https://notcve.org/view.php?id=CVE-2024-44965
In the Linux kernel, the following vulnerability has been resolved: x86/mm: Fix pti_clone_pgtable() alignment assumption Guenter reported dodgy crashes on an i386-nosmp build using GCC-11 that had the form of endless traps until entry stack exhaust and then #DF from the stack guard. It turned out that pti_clone_pgtable() had alignment assumptions on the start address, notably it hard assumes start is PMD aligned. This is true on x86_64, but very much not true on i386. These assumptions can cause the end condition to malfunction, leading to a 'short' clone. Guess what happens when the user mapping has a short copy of the entry text? Use the correct increment form for addr to avoid alignment assumptions. • https://git.kernel.org/stable/c/16a3fe634f6a568c6234b8747e5d50487fed3526 https://git.kernel.org/stable/c/18da1b27ce16a14a9b636af9232acb4fb24f4c9e https://git.kernel.org/stable/c/25a727233a40a9b33370eec9f0cad67d8fd312f8 https://git.kernel.org/stable/c/d00c9b4bbc442d99e1dafbdfdab848bc1ead73f6 https://git.kernel.org/stable/c/4d143ae782009b43b4f366402e5c37f59d4e4346 https://git.kernel.org/stable/c/5c580c1050bcbc15c3e78090859d798dcf8c9763 https://git.kernel.org/stable/c/ca07aab70dd3b5e7fddb62d7a6ecd7a7d6d0b2ed https://git.kernel.org/stable/c/df3eecb5496f87263d171b254ca6e2758 •
