CVE-2024-53682 |
Description: In the Linux kernel, the following vulnerability has been resolved:
regulator: axp20x: AXP717: set ramp_delay
AXP717 datasheet says that regulator ramp delay is 15.625 us/step,
which is 10mV in our case.
Add a AXP_DESC_RANGES_DELAY macro and update AXP_DESC_RANGES macro to
expand to AXP_DESC_RANGES_DELAY with ramp_delay = 0
For DCDC4, steps is 100mv
Add a AXP_DESC_DELAY macro and update AXP_DESC macro to
expand to AXP_DESC_DELAY with ramp_delay = 0
This patch fix crashes when using CPU DVFS.

CVE-2024-53680 |
Description: In the Linux kernel, the following vulnerability has been resolved:
ipvs: fix UB due to uninitialized stack access in ip_vs_protocol_init()
Under certain kernel configurations when building with Clang/LLVM, the
compiler does not generate a return or jump as the terminator
instruction for ip_vs_protocol_init(), triggering the following objtool
warning during build time:
vmlinux.o: warning: objtool: ip_vs_protocol_init() falls through to next function __initstub__kmod_ip_vs_rr__935_123_ip_vs_rr_init6()
At runtime, this either causes an oops when trying to load the ipvs
module or a boot-time panic if ipvs is built-in. This same issue has
been reported by the Intel kernel test robot previously.
Digging deeper into both LLVM and the kernel code reveals this to be a
undefined behavior problem. ip_vs_protocol_init() uses a on-stack buffer
of 64 chars to store the registered protocol names and leaves it
uninitialized after definition. The function calls strnlen() when
concatenating protocol names into the buffer. With CONFIG_FORTIFY_SOURCE
strnlen() performs an extra step to check whether the last byte of the
input char buffer is a null character (commit 3009f891bb9f ("fortify:
Allow strlen() and strnlen() to pass compile-time known lengths")).
This, together with possibly other configurations, cause the following
IR to be generated:
define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #5 section ".init.text" align 16 !kcfi_type !29 {
%1 = alloca [64 x i8], al...

CVE-2024-52332 |
Description: In the Linux kernel, the following vulnerability has been resolved:
igb: Fix potential invalid memory access in igb_init_module()
The pci_register_driver() can fail and when this happened, the dca_notifier
needs to be unregistered, otherwise the dca_notifier can be called when
igb fails to install, resulting to invalid memory access.

CVE-2024-52319 |
Description: In the Linux kernel, the following vulnerability has been resolved:
mm: use aligned address in clear_gigantic_page()
In current kernel, hugetlb_no_page() calls folio_zero_user() with the
fault address. Where the fault address may be not aligned with the huge
page size. Then, folio_zero_user() may call clear_gigantic_page() with
the address, while clear_gigantic_page() requires the address to be huge
page size aligned. So, this may cause memory corruption or information
leak, addtional, use more obvious naming 'addr_hint' instead of 'addr' for
clear_gigantic_page().

CVE-2024-51729 |
Description: In the Linux kernel, the following vulnerability has been resolved:
mm: use aligned address in copy_user_gigantic_page()
In current kernel, hugetlb_wp() calls copy_user_large_folio() with the
fault address. Where the fault address may be not aligned with the huge
page size. Then, copy_user_large_folio() may call
copy_user_gigantic_page() with the address, while
copy_user_gigantic_page() requires the address to be huge page size
aligned. So, this may cause memory corruption or information leak,
addtional, use more obvious naming 'addr_hint' instead of 'addr' for
copy_user_gigantic_page().

CVE-2024-50051 |
Description: In the Linux kernel, the following vulnerability has been resolved:
spi: mpc52xx: Add cancel_work_sync before module remove
If we remove the module which will call mpc52xx_spi_remove
it will free 'ms' through spi_unregister_controller.
while the work ms->work will be used. The sequence of operations
that may lead to a UAF bug.
Fix it by ensuring that the work is canceled before proceeding with
the cleanup in mpc52xx_spi_remove.

CVE-2024-49573 |
Description: In the Linux kernel, the following vulnerability has been resolved:
sched/fair: Fix NEXT_BUDDY
Adam reports that enabling NEXT_BUDDY insta triggers a WARN in
pick_next_entity().
Moving clear_buddies() up before the delayed dequeue bits ensures
no ->next buddy becomes delayed. Further ensure no new ->next buddy
ever starts as delayed.

CVE-2024-49571 |
Description: In the Linux kernel, the following vulnerability has been resolved:
net/smc: check iparea_offset and ipv6_prefixes_cnt when receiving proposal msg
When receiving proposal msg in server, the field iparea_offset
and the field ipv6_prefixes_cnt in proposal msg are from the
remote client and can not be fully trusted. Especially the
field iparea_offset, once exceed the max value, there has the
chance to access wrong address, and crash may happen.
This patch checks iparea_offset and ipv6_prefixes_cnt before using them.
