| In the Linux kernel, the following vulnerability has been resolved:
net: macb: fix use after free on rmmod
plat_dev->dev->platform_data is released by platform_device_unregister(),
use of pclk and hclk is a use-after-free. Since device unregister won't
need a clk device we adjust the function call sequence to fix this issue.
[ 31.261225] BUG: KASAN: use-after-free in macb_remove+0x77/0xc6 [macb_pci]

| In the Linux kernel, the following vulnerability has been resolved:
usb: fix various gadget panics on 10gbps cabling
usb_assign_descriptors() is called with 5 parameters,
the last 4 of which are the usb_descriptor_header for:
full-speed (USB1.1 - 12Mbps [including USB1.0 low-speed @ 1.5Mbps),
high-speed (USB2.0 - 480Mbps),
super-speed (USB3.0 - 5Gbps),
super-speed-plus (USB3.1 - 10Gbps).
The differences between full/high/super-speed descriptors are usually
substantial (due to changes in the maximum usb block size from 64 to 512
to 1024 bytes and other differences in the specs), while the difference
between 5 and 10Gbps descriptors may be as little as nothing
(in many cases the same tuning is simply good enough).
However if a gadget driver calls usb_assign_descriptors() with
a NULL descriptor for super-speed-plus and is then used on a max 10gbps
configuration, the kernel will crash with a null pointer dereference,
when a 10gbps capable device port + cable + host port combination shows up.
(This wouldn't happen if the gadget max-speed was set to 5gbps, but
it of course defaults to the maximum, and there's no real reason to
artificially limit it)
The fix is to simply use the 5gbps descriptor as the 10gbps descriptor,
if a 10gbps descriptor wasn't provided.
Obviously this won't fix the problem if the 5gbps descriptor is also
NULL, but such cases can't be so trivially solved (and any such gadgets
are unlikely to be used with USB3 ports any way). |
| In the Linux kernel, the following vulnerability has been resolved:
gfs2: Fix use-after-free in gfs2_glock_shrink_scan
The GLF_LRU flag is checked under lru_lock in gfs2_glock_remove_from_lru() to
remove the glock from the lru list in __gfs2_glock_put().
On the shrink scan path, the same flag is cleared under lru_lock but because
of cond_resched_lock(&lru_lock) in gfs2_dispose_glock_lru(), progress on the
put side can be made without deleting the glock from the lru list.
Keep GLF_LRU across the race window opened by cond_resched_lock(&lru_lock) to
ensure correct behavior on both sides - clear GLF_LRU after list_del under
lru_lock. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: musb: tusb6010: check return value after calling platform_get_resource()
It will cause null-ptr-deref if platform_get_resource() returns NULL,
we need check the return value. |
| In the Linux kernel, the following vulnerability has been resolved:
x86/kvm: Teardown PV features on boot CPU as well
Various PV features (Async PF, PV EOI, steal time) work through memory
shared with hypervisor and when we restore from hibernation we must
properly teardown all these features to make sure hypervisor doesn't
write to stale locations after we jump to the previously hibernated kernel
(which can try to place anything there). For secondary CPUs the job is
already done by kvm_cpu_down_prepare(), register syscore ops to do
the same for boot CPU. |
| In the Linux kernel, the following vulnerability has been resolved:
x86/kvm: Disable kvmclock on all CPUs on shutdown
Currenly, we disable kvmclock from machine_shutdown() hook and this
only happens for boot CPU. We need to disable it for all CPUs to
guard against memory corruption e.g. on restore from hibernate.
Note, writing '0' to kvmclock MSR doesn't clear memory location, it
just prevents hypervisor from updating the location so for the short
while after write and while CPU is still alive, the clock remains usable
and correct so we don't need to switch to some other clocksource. |
| In the Linux kernel, the following vulnerability has been resolved:
phonet/pep: refuse to enable an unbound pipe
This ioctl() implicitly assumed that the socket was already bound to
a valid local socket name, i.e. Phonet object. If the socket was not
bound, two separate problems would occur:
1) We'd send an pipe enablement request with an invalid source object.
2) Later socket calls could BUG on the socket unexpectedly being
connected yet not bound to a valid object. |
| In affected versions of Octopus Deploy it is possible to bypass rate limiting on login using null bytes. |
| drivers/char/pcmcia/synclink_cs.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free if a physically proximate attacker removes a PCMCIA device while calling ioctl, aka a race condition between mgslpc_ioctl and mgslpc_detach. |
| Joplin version 2.8.8 allows an external attacker to execute arbitrary commands remotely on any client that opens a link in a malicious markdown file, via Joplin. This is possible because the application does not properly validate the schema/protocol of existing links in the markdown file before passing them to the 'shell.openExternal' function. |
| Gridea version 0.9.3 allows an external attacker to execute arbitrary code remotely on any client attempting to view a malicious markdown file through Gridea. This is possible because the application has the 'nodeIntegration' option enabled. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: nl80211: don't free NULL coalescing rule
If the parsing fails, we can dereference a NULL pointer here. |
| An issue was discovered in Hashicorp Packer before 2.3.1. The recommended sudoers configuration for Vagrant on Linux is insecure. If the host has been configured according to this documentation, non-privileged users on the host can leverage a wildcard in the sudoers configuration to execute arbitrary commands as root. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: avoid reading out of bounds when loading TX power FW elements
Because the loop-expression will do one more time before getting false from
cond-expression, the original code copied one more entry size beyond valid
region.
Fix it by moving the entry copy to loop-body. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btnxpuart: Shutdown timer and prevent rearming when driver unloading
When unload the btnxpuart driver, its associated timer will be deleted.
If the timer happens to be modified at this moment, it leads to the
kernel call this timer even after the driver unloaded, resulting in
kernel panic.
Use timer_shutdown_sync() instead of del_timer_sync() to prevent rearming.

| In the Linux kernel, the following vulnerability has been resolved:
s390/pkey: Wipe copies of clear-key structures on failure
Wipe all sensitive data from stack for all IOCTLs, which convert a
clear-key into a protected- or secure-key. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix a race condition of vram buffer unref in svm code
prange->svm_bo unref can happen in both mmu callback and a callback after
migrate to system ram. Both are async call in different tasks. Sync svm_bo
unref operation to avoid random "use-after-free". |
| In the Linux kernel, the following vulnerability has been resolved:
net: atlantic: eliminate double free in error handling logic
Driver has a logic leak in ring data allocation/free,
where aq_ring_free could be called multiple times on same ring,
if system is under stress and got memory allocation error.
Ring pointer was used as an indicator of failure, but this is
not correct since only ring data is allocated/deallocated.
Ring itself is an array member.
Changing ring allocation functions to return error code directly.
This simplifies error handling and eliminates aq_ring_free
on higher layer. |
| In the Linux kernel, the following vulnerability has been resolved:
block/rnbd-srv: Check for unlikely string overflow
Since "dev_search_path" can technically be as large as PATH_MAX,
there was a risk of truncation when copying it and a second string
into "full_path" since it was also PATH_MAX sized. The W=1 builds were
reporting this warning:
drivers/block/rnbd/rnbd-srv.c: In function 'process_msg_open.isra':
drivers/block/rnbd/rnbd-srv.c:616:51: warning: '%s' directive output may be truncated writing up to 254 bytes into a region of size between 0 and 4095 [-Wformat-truncation=]
616 | snprintf(full_path, PATH_MAX, "%s/%s",
| ^~
In function 'rnbd_srv_get_full_path',
inlined from 'process_msg_open.isra' at drivers/block/rnbd/rnbd-srv.c:721:14: drivers/block/rnbd/rnbd-srv.c:616:17: note: 'snprintf' output between 2 and 4351 bytes into a destination of size 4096
616 | snprintf(full_path, PATH_MAX, "%s/%s",
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
617 | dev_search_path, dev_name);
| ~~~~~~~~~~~~~~~~~~~~~~~~~~
To fix this, unconditionally check for truncation (as was already done
for the case where "%SESSNAME%" was present). |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: wfx: fix possible NULL pointer dereference in wfx_set_mfp_ap()
Since 'ieee80211_beacon_get()' can return NULL, 'wfx_set_mfp_ap()'
should check the return value before examining skb data. So convert
the latter to return an appropriate error code and propagate it to
return from 'wfx_start_ap()' as well. Compile tested only. |
