https://notcve.org/view.php?id=CVE-2024-45030
In the Linux kernel, the following vulnerability has been resolved: igb: cope with large MAX_SKB_FRAGS Sabrina reports that the igb driver does not cope well with large MAX_SKB_FRAG values: setting MAX_SKB_FRAG to 45 causes payload corruption on TX. An easy reproducer is to run ssh to connect to the machine. With MAX_SKB_FRAGS=17 it works, with MAX_SKB_FRAGS=45 it fails. This has been reported originally in https://bugzilla.redhat.com/show_bug.cgi?id=2265320 The root cause of the issue is that the driver does not take into account properly the (possibly large) shared info size when selecting the ring layout, and will try to fit two packets inside the same 4K page even when the 1st fraglist will trump over the 2nd head. Address the issue by checking if 2K buffers are insufficient. • https://git.kernel.org/stable/c/3948b05950fdd64002a5f182c65ba5cf2d53cf71 https://git.kernel.org/stable/c/8ea80ff5d8298356d28077bc30913ed37df65109 https://git.kernel.org/stable/c/b52bd8bcb9e8ff250c79b44f9af8b15cae8911ab https://git.kernel.org/stable/c/8aba27c4a5020abdf60149239198297f88338a8d •

https://notcve.org/view.php?id=CVE-2024-45029
In the Linux kernel, the following vulnerability has been resolved: i2c: tegra: Do not mark ACPI devices as irq safe On ACPI machines, the tegra i2c module encounters an issue due to a mutex being called inside a spinlock. This leads to the following bug: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:585 ... Call trace: __might_sleep __mutex_lock_common mutex_lock_nested acpi_subsys_runtime_resume rpm_resume tegra_i2c_xfer The problem arises because during __pm_runtime_resume(), the spinlock &dev->power.lock is acquired before rpm_resume() is called. Later, rpm_resume() invokes acpi_subsys_runtime_resume(), which relies on mutexes, triggering the error. To address this issue, devices on ACPI are now marked as not IRQ-safe, considering the dependency of acpi_subsys_runtime_resume() on mutexes. • https://git.kernel.org/stable/c/bd2fdedbf2bac27f4a2ac16b84ab9b9e5f67006c https://git.kernel.org/stable/c/a89aef1e6cc43fa019a58080ed05c839e6c77876 https://git.kernel.org/stable/c/6861faf4232e4b78878f2de1ed3ee324ddae2287 https://git.kernel.org/stable/c/2853e1376d8161b04c9ff18ba82b43f08a049905 https://git.kernel.org/stable/c/14d069d92951a3e150c0a81f2ca3b93e54da913b •

https://notcve.org/view.php?id=CVE-2024-45026
In the Linux kernel, the following vulnerability has been resolved: s390/dasd: fix error recovery leading to data corruption on ESE devices Extent Space Efficient (ESE) or thin provisioned volumes need to be formatted on demand during usual IO processing. The dasd_ese_needs_format function checks for error codes that signal the non existence of a proper track format. The check for incorrect length is to imprecise since other error cases leading to transport of insufficient data also have this flag set. This might lead to data corruption in certain error cases for example during a storage server warmstart. Fix by removing the check for incorrect length and replacing by explicitly checking for invalid track format in transport mode. Also remove the check for file protected since this is not a valid ESE handling case. • https://git.kernel.org/stable/c/5e2b17e712cf10cc3cc98fde28a88e8f1a1267e9 https://git.kernel.org/stable/c/19f60a55b2fda49bc4f6134a5f6356ef62ee69d8 https://git.kernel.org/stable/c/e245a18281c252c8dbc467492e09bb5d4b012118 https://git.kernel.org/stable/c/a665e3b7ac7d5cdc26e00e3d0fc8fd490e00316a https://git.kernel.org/stable/c/0a228896a1b3654cd461ff654f6a64e97a9c3246 https://git.kernel.org/stable/c/93a7e2856951680cd7fe6ebd705ac10c8a8a5efd https://git.kernel.org/stable/c/5d4a304338daf83ace2887aaacafd66fe99ed5cc https://git.kernel.org/stable/c/7db4042336580dfd75cb5faa82c12cd51 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-45025 – fix bitmap corruption on close_range() with CLOSE_RANGE_UNSHARE
https://notcve.org/view.php?id=CVE-2024-45025
In the Linux kernel, the following vulnerability has been resolved: fix bitmap corruption on close_range() with CLOSE_RANGE_UNSHARE copy_fd_bitmaps(new, old, count) is expected to copy the first count/BITS_PER_LONG bits from old->full_fds_bits[] and fill the rest with zeroes. What it does is copying enough words (BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest. That works fine, *if* all bits past the cutoff point are clear. Otherwise we are risking garbage from the last word we'd copied. For most of the callers that is true - expand_fdtable() has count equal to old->max_fds, so there's no open descriptors past count, let alone fully occupied words in ->open_fds[], which is what bits in ->full_fds_bits[] correspond to. The other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds), which is the smallest multiple of BITS_PER_LONG that covers all opened descriptors below max_fds. In the common case (copying on fork()) max_fds is ~0U, so all opened descriptors will be below it and we are fine, by the same reasons why the call in expand_fdtable() is safe. Unfortunately, there is a case where max_fds is less than that and where we might, indeed, end up with junk in ->full_fds_bits[] - close_range(from, to, CLOSE_RANGE_UNSHARE) with * descriptor table being currently shared * 'to' being above the current capacity of descriptor table * 'from' being just under some chunk of opened descriptors. In that case we end up with observably wrong behaviour - e.g. spawn a child with CLONE_FILES, get all descriptors in range 0..127 open, then close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending up with descriptor #128, despite #64 being observably not open. The minimally invasive fix would be to deal with that in dup_fd(). If this proves to add measurable overhead, we can go that way, but let's try to fix copy_fd_bitmaps() first. * new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size). * make copy_fd_bitmaps() take the bitmap size in words, rather than bits; it's 'count' argument is always a multiple of BITS_PER_LONG, so we are not losing any information, and that way we can use the same helper for all three bitmaps - compiler will see that count is a multiple of BITS_PER_LONG for the large ones, so it'll generate plain memcpy()+memset().
