https://notcve.org/view.php?id=CVE-2024-56627
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix Out-of-Bounds Read in ksmbd_vfs_stream_read An offset from client could be a negative value, It could lead to an out-of-bounds read from the stream_buf. Note that this issue is coming when setting 'vfs objects = streams_xattr parameter' in ksmbd.conf. • https://git.kernel.org/stable/c/de4d790dcf53be41736239d7ee63849a16ff5d10 https://git.kernel.org/stable/c/27de4295522e9a33e4a3fc72f7b8193df9eebe41 https://git.kernel.org/stable/c/81eed631935f2c52cdaf6691c6d48e0b06e8ad73 https://git.kernel.org/stable/c/fc342cf86e2dc4d2edb0fc2ff5e28b6c7845adb9 •

CVSS: -EPSS: 0%CPEs: 6EXPL: 0CVE-2024-56623 – scsi: qla2xxx: Fix use after free on unload
https://notcve.org/view.php?id=CVE-2024-56623
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix use after free on unload System crash is observed with stack trace warning of use after free. There are 2 signals to tell dpc_thread to terminate (UNLOADING flag and kthread_stop). On setting the UNLOADING flag when dpc_thread happens to run at the time and sees the flag, this causes dpc_thread to exit and clean up itself. When kthread_stop is called for final cleanup, this causes use after free. Remove UNLOADING signal to terminate dpc_thread. Use the kthread_stop as the main signal to exit dpc_thread.

CVSS: -EPSS: 0%CPEs: 7EXPL: 0CVE-2024-56619 – nilfs2: fix potential out-of-bounds memory access in nilfs_find_entry()
https://notcve.org/view.php?id=CVE-2024-56619
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix potential out-of-bounds memory access in nilfs_find_entry() Syzbot reported that when searching for records in a directory where the inode's i_size is corrupted and has a large value, memory access outside the folio/page range may occur, or a use-after-free bug may be detected if KASAN is enabled. This is because nilfs_last_byte(), which is called by nilfs_find_entry() and others to calculate the number of valid bytes of directory data in a page from i_size and the page index, loses the upper 32 bits of the 64-bit size information due to an inappropriate type of local variable to which the i_size value is assigned. This caused a large byte offset value due to underflow in the end address calculation in the calling nilfs_find_entry(), resulting in memory access that exceeds the folio/page size. Fix this issue by changing the type of the local variable causing the bit loss from "unsigned int" to "u64". The return value of nilfs_last_byte() is also of type "unsigned int", but it is truncated so as not to exceed PAGE_SIZE and no bit loss occurs, so no change is required. • https://git.kernel.org/stable/c/2ba466d74ed74f073257f86e61519cb8f8f46184 https://git.kernel.org/stable/c/09d6d05579fd46e61abf6e457bb100ff11f3a9d3 https://git.kernel.org/stable/c/e3732102a9d638d8627d14fdf7b208462f0520e0 https://git.kernel.org/stable/c/48eb6e7404948032bbe811c5affbe39f6b316951 https://git.kernel.org/stable/c/5af8366625182f01f6d8465c9a3210574673af57 https://git.kernel.org/stable/c/c3afea07477baccdbdec4483f8d5e59d42a3f67f https://git.kernel.org/stable/c/31f7b57a77d4c82a34ddcb6ff35b5aa577ef153e https://git.kernel.org/stable/c/985ebec4ab0a28bb5910c3b1481a40fbf •
CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-56616 – drm/dp_mst: Fix MST sideband message body length check
https://notcve.org/view.php?id=CVE-2024-56616
In the Linux kernel, the following vulnerability has been resolved: drm/dp_mst: Fix MST sideband message body length check Fix the MST sideband message body length check, which must be at least 1 byte accounting for the message body CRC (aka message data CRC) at the end of the message. This fixes a case where an MST branch device returns a header with a correct header CRC (indicating a correctly received body length), with the body length being incorrectly set to 0. This will later lead to a memory corruption in drm_dp_sideband_append_payload() and the following errors in dmesg: UBSAN: array-index-out-of-bounds in drivers/gpu/drm/display/drm_dp_mst_topology.c:786:25 index -1 is out of range for type 'u8 [48]' Call Trace: drm_dp_sideband_append_payload+0x33d/0x350 [drm_display_helper] drm_dp_get_one_sb_msg+0x3ce/0x5f0 [drm_display_helper] drm_dp_mst_hpd_irq_handle_event+0xc8/0x1580 [drm_display_helper] memcpy: detected field-spanning write (size 18446744073709551615) of single field "&msg->msg[msg->curlen]" at drivers/gpu/drm/display/drm_dp_mst_topology.c:791 (size 256) Call Trace: drm_dp_sideband_append_payload+0x324/0x350 [drm_display_helper] drm_dp_get_one_sb_msg+0x3ce/0x5f0 [drm_display_helper] drm_dp_mst_hpd_irq_handle_event+0xc8/0x1580 [drm_display_helper] • https://git.kernel.org/stable/c/780fa184d4dc38ad6c4fded345ab8f9be7a63e96 https://git.kernel.org/stable/c/c58947a8d4a500902597ee1dbadf0518d7ff8801 https://git.kernel.org/stable/c/1fc1f32c4a3421b9d803f18ec3ef49db2fb5d5ef https://git.kernel.org/stable/c/bd2fccac61b40eaf08d9546acc9fef958bfe4763 •
