    udf: Do not bother merging very long extents

    In the Linux kernel, the following vulnerability has been resolved: udf: Do not bother merging very long extents When merging very long extents we try to push as much length as possible to the first extent. However this is unnecessarily complicated and not really worth the trouble. Furthermore there was a bug in the logic resulting in corrupting extents in the file as syzbot reproducer shows. So just don't bother with the merging of extents that are too long together.

    ext4: allow ext4_get_group_info() to fail

    In the Linux kernel, the following vulnerability has been resolved: ext4: allow ext4_get_group_info() to fail Previously, ext4_get_group_info() would treat an invalid group number as BUG(), since in theory it should never happen. However, if a malicious attaker (or fuzzer) modifies the superblock via the block device while it is the file system is mounted, it is possible for s_first_data_block to get set to a very large number. In that case, when calculating the block group of some block number (such as the starting block of a preallocation region), could result in an underflow and very large block group number. Then the BUG_ON check in

    start_kernel: Add __no_stack_protector function attribute

    In the Linux kernel, the following vulnerability has been resolved: start_kernel: Add __no_stack_protector function attribute Back during the discussion of commit a9a3ed1eff36 ("x86: Fix early boot crash on gcc-10, third try") we discussed the need for a function attribute to control the omission of stack protectors on a per-function basis; at the time Clang had support for no_stack_protector but GCC did not. This was fixed in gcc-11. Now that the function attribute is available, let's start using it. Callers of boot_init_stack_canary need to use this function attribute unless they're compiled with -fno-stack-protector, otherwise the canar

    In the Linux kernel, the following vulnerability has been resolved: MIPS: vpe-mt: fix possible memory leak while module exiting Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's bus_id string array"), the name of device is allocated dynamically, it need be freed when module exiting, call put_device() to give up reference, so that it can be freed in kobject_cleanup() when the refcount hit to 0. The vpe_device is static, so remove kfree() from vpe_device_release().

    btrfs: fix resolving backrefs for inline extent followed by prealloc

    In the Linux kernel, the following vulnerability has been resolved: btrfs: fix resolving backrefs for inline extent followed by prealloc If a file consists of an inline extent followed by a regular or prealloc extent, then a legitimate attempt to resolve a logical address in the non-inline region will result in add_all_parents reading the invalid offset field of the inline extent. If the inline extent item is placed in the leaf eb s.t. it is the first item, attempting to access the offset field will not only be meaningless, it will go past the end of the eb and cause this panic: [17.626048] BTRFS warning (device dm-2): bad eb member end:

    lib: cpu_rmap: Avoid use after free on rmap->obj array entries

    In the Linux kernel, the following vulnerability has been resolved: lib: cpu_rmap: Avoid use after free on rmap->obj array entries When calling irq_set_affinity_notifier() with NULL at the notify argument, it will cause freeing of the glue pointer in the corresponding array entry but will leave the pointer in the array. A subsequent call to free_irq_cpu_rmap() will try to free this entry again leading to possible use after free. Fix that by setting NULL to the array entry and checking that we have non-zero at the array entry when iterating over the array in free_irq_cpu_rmap(). The current code does not suffer from this since there are no

    In the Linux kernel, the following vulnerability has been resolved: media: cx23885: Fix a null-ptr-deref bug in buffer_prepare() and buffer_finish() When the driver calls cx23885_risc_buffer() to prepare the buffer, the function call dma_alloc_coherent may fail, resulting in a empty buffer risc->cpu. Later when we free the buffer or access the buffer, null ptr deref is triggered. This bug is similar to the following one: https://git.linuxtv.org/media_stage.git/commit/?id=2b064d91440b33fba5b452f2d1b31f13ae911d71.

    scsi: qla4xxx: Add length check when parsing nlattrs

    In the Linux kernel, the following vulnerability has been resolved: scsi: qla4xxx: Add length check when parsing nlattrs There are three places that qla4xxx parses nlattrs: - qla4xxx_set_chap_entry() - qla4xxx_iface_set_param() - qla4xxx_sysfs_ddb_set_param() and each of them directly converts the nlattr to specific pointer of structure without length checking. This could be dangerous as those attributes are not validated and a malformed nlattr (e.g., length 0) could result in an OOB read that leaks heap dirty data. Add the nla_len check before accessing the nlattr data and return EINVAL if the length check fails.

    In the Linux kernel, the following vulnerability has been resolved: HID: multitouch: Correct devm device reference for hidinput input_dev name Reference the HID device rather than the input device for the devm allocation of the input_dev name. Referencing the input_dev would lead to a use-after-free when the input_dev was unregistered and subsequently fires a uevent that depends on the name. At the point of firing the uevent, the name would be freed by devres management. Use devm_kasprintf to simplify the logic for allocating memory and formatting the input_dev name string.
