In unregister_fprobe function we can't release fp->rethook while it's
possible there are some of its users still running on another cpu.
Moving rethook_free call after fp->ops is unregistered with
unregister_ftrace_function call. |
| In the Linux kernel, the following vulnerability has been resolved:
ip_vti: fix potential slab-use-after-free in decode_session6
When ip_vti device is set to the qdisc of the sfb type, the cb field
of the sent skb may be modified during enqueuing. Then,
slab-use-after-free may occur when ip_vti device sends IPv6 packets.
As commit f855691975bb ("xfrm6: Fix the nexthdr offset in
_decode_session6.") showed, xfrm_decode_session was originally intended
only for the receive path. IP6CB(skb)->nhoff is not set during
transmission. Therefore, set the cb field in the skb to 0 before
sending packets. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/zcrypt: don't leak memory if dev_set_name() fails
When dev_set_name() fails, zcdn_create() doesn't free the newly
allocated resources. Do it. |
| In the Linux kernel, the following vulnerability has been resolved:
ext2: Check block size validity during mount
Check that log of block size stored in the superblock has sensible
value. Otherwise the shift computing the block size can overflow leading
to undefined behavior. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: rs9: Fix suspend/resume
Disabling the cache in commit 2ff4ba9e3702 ("clk: rs9: Fix I2C accessors")
without removing cache synchronization in resume path results in a
kernel panic as map->cache_ops is unset, due to REGCACHE_NONE.
Enable flat cache again to support resume again. num_reg_defaults_raw
is necessary to read the cache defaults from hardware. Some registers
are strapped in hardware and cannot be provided in software. |

It is because that skb->len requires at least sizeof(struct qrtr_ctrl_pkt)
in qrtr_tx_resume(). And skb->len equals to size in qrtr_endpoint_post().
But size is less than sizeof(struct qrtr_ctrl_pkt) when qrtr_cb->type
equals to QRTR_TYPE_RESUME_TX in qrtr_endpoint_post() under the syzbot
scenario. This triggers the uninit variable access bug.
Add size check when qrtr_cb->type equals to QRTR_TYPE_RESUME_TX in
qrtr_endpoint_post() to fix the bug. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: don't trust firmware n_channels
If the firmware sends us a corrupted MCC response with
n_channels much larger than the command response can be,
we might copy far too much (uninitialized) memory and
even crash if the n_channels is large enough to make it
run out of the one page allocated for the FW response.
Fix that by checking the lengths. Doing a < comparison
would be sufficient, but the firmware should be doing
it correctly, so check more strictly. |
| In the Linux kernel, the following vulnerability has been resolved:
bus: mhi: host: Range check CHDBOFF and ERDBOFF
If the value read from the CHDBOFF and ERDBOFF registers is outside the
range of the MHI register space then an invalid address might be computed
which later causes a kernel panic. Range check the read value to prevent
a crash due to bad data from the device. |
| In the Linux kernel, the following vulnerability has been resolved:
bonding: do not assume skb mac_header is set
Drivers must not assume in their ndo_start_xmit() that
skbs have their mac_header set. skb->data is all what is needed.

indeed the driver does not hold rtnl_lock during its internal close

a huge bug as the driver implements its own locking, and does not
implement changing the number of queues, but we need to silence
the splat. |

media: dvb-core: Fix double free in dvb_register_device()
In function dvb_register_device() -> dvb_register_media_device() ->
dvb_create_media_entity(), dvb->entity is allocated and initialized. If
the initialization fails, it frees the dvb->entity, and return an error
code. The caller takes the error code and handles the error by calling
dvb_media_device_free(), which unregisters the entity and frees the
field again if it is not NULL. As dvb->entity may not NULLed in
dvb_create_media_entity() when the allocation of dvbdev->pad fails, a
double free may occur. This may also cause an Use After free in
media_device_unregister_entity().
Fix this by storing NULL to dvb->entity when it is freed. |
